-<p>  <b>SiSU</b> is a framework for document
-structuring, publishing (in multiple open standard formats) and search,
-comprising of: (a) a lightweight document structure and presentation markup
-syntax; and (b) an accompanying engine for generating standard document
-format outputs from documents prepared in sisu markup syntax, which is
-able to produce multiple standard outputs (including the population of
-sql databases) that (can) share a common numbering system for the citation
-of text within a document.
-<p>  <b>SiSU</b> is developed under an open source, software
-libre license ( <i>GPLv3</i> ). Its use case for development is work with medium
-to large document sets and cope with evolving document formats/ representation
-technologies. Documents are prepared once, and generated as need be to update
-the technical presentation or add additional output formats. Various output
-formats (including search related output) share a common mechanism for
-cross-output-format citation.
-<p>  <b>SiSU</b> both defines a markup syntax and provides
-an engine that produces open standards format outputs from documents prepared
-with <b>SiSU</b> markup. From a single lightly prepared document sisu custom builds
-several standard output formats which share a common (text object) numbering
-system for citation of content within a document (that also has implications
-for search). The sisu engine works with an abstraction of the document&rsquo;s
-structure and content from which it is possible to generate different forms
-of representation of the document. Significantly <b>SiSU</b> markup is more sparse
-than html and outputs which include <i>HTML,</i> <i>EPUB,</i> <i>ODT</i> (Open Document Format
-text), <i>LaTeX,</i> landscape and portrait <i>PDF,</i> all of which can be added to
-and updated. <b>SiSU</b> is also able to populate <i>SQL</i> type databases at an object
-level, which means that searches can be made with that degree of granularity.
-
-<p>  Source document preparation and output generation is a two step process:
-(i) document source is prepared, that is, marked up in sisu markup syntax
-and (ii) the desired output subsequently generated by running the sisu
-engine against document source. Output representations if updated (in the
-sisu engine) can be generated by re-running the engine against the prepared
-source. Using <b>SiSU</b> markup applied to a document, <b>SiSU</b> custom builds (to
-take advantage of the strengths of different ways of representing documents)
-various standard open output formats including plain text, <i>HTML,</i> <i>XHTML,</i>
-<i>XML,</i> <i>EPUB,</i> <i>ODT,</i> <i>LaTeX</i> or <i>PDF</i> files, and populate an <i>SQL</i> database with objects[^1]
-(equating generally to paragraph-sized chunks) so searches may be performed
-and matches returned with that degree of granularity ( e.g. your search criteria
-is met by these documents and at these locations within each document).
-Document output formats share a common object numbering system for locating
-content. This is particularly suitable for "published" works (finalized
-texts as opposed to works that are frequently changed or updated) for which
-it provides a fixed means of reference of content.
-<p>  In preparing a <b>SiSU</b>
-document you optionally provide semantic information related to the document
-in a document header, and in marking up the substantive text provide information
-on the structure of the document, primarily indicating heading levels and
-footnotes. You also provide information on basic text attributes where used.
-The rest is automatic, sisu from this information custom builds[^2] the
-different forms of output requested.
-<p>  <b>SiSU</b> works with an abstraction of
-the document based on its structure which is comprised of its headings[^3]
-and objects[^4], which enables <b>SiSU</b> to represent the document in many different
-ways, and to take advantage of the strengths of different ways of presenting
-documents. The objects are numbered, and these numbers can be used to provide
-a common basis for citing material within a document across the different
-output format types. This is significant as page numbers are not well suited
-to the digital age, in web publishing, changing a browser&rsquo;s default font
-or using a different browser can mean that text will appear on a different
-page; and publishing in different formats, html, landscape and portrait
-pdf etc. again page numbers are not useful to cite text. Dealing with documents
-at an object level together with object numbering also has implications
-for search that <b>SiSU</b> is able to take advantage of.
-<p>  One of the challenges
-of maintaining documents is to keep them in a format that allows use of
-them independently of proprietary platforms. Consider issues related to
-dealing with legacy proprietary formats today and what guarantee you have
-that old proprietary formats will remain (or can be read without proprietary
-software/equipment) in 15 years time, or the way the way in which html
-has evolved over its relatively short span of existence. <b>SiSU</b> provides the
-flexibility of producing documents in multiple non-proprietary open formats
-including <i>HTML,</i> <i>EPUB,</i> [^5] <i>ODT,</i> [^6] <i>PDF</i> [^7] <i>ODF,</i> [^8]. Whilst <b>SiSU</b> relies
-on software, the markup is uncomplicated and minimalistic which guarantees
-that future engines can be written to run against it. It is also easily
-converted to other formats, which means documents prepared in <b>SiSU</b> can
-be migrated to other document formats. Further security is provided by the
-fact that the software itself, <b>SiSU</b> is available under <i>GPLv3</i> a licence
-that guarantees that the source code will always be open, and free as in
-libre, which means that that code base can be used, updated and further
-developed as required under the terms of its license. Another challenge
-is to keep up with a moving target. <b>SiSU</b> permits new forms of output to
-be added as they become important, (Open Document Format text was added
-in 2006 when it became an ISO standard for office applications and the
-archival of documents), <i>EPUB</i> was introduced in 2009; and allows the technical
-representations existing output to be updated ( <i>HTML</i> has evolved and the
-related module has been updated repeatedly over the years, presumably when
-the World Wide Web Consortium (w3c) finalises <i>HTML</i> 5 which is currently
-under development, the <i>HTML</i> module will again be updated allowing all existing
-documents to be regenerated as <i>HTML</i> 5).
-<p>  The document formats are written
-to the file-system and available for indexing by independent indexing tools,
-whether off the web like Google and Yahoo or on the site like Lucene and
-Hyperestraier.
-<p>  <b>SiSU</b> also provides other features such as concordance files
-and document content certificates, and the working against an abstraction
-of document structure has further possibilities for the research and development
-of other document representations, the availability of objects is useful
-for example for topic maps and thesauri, together with the flexibility
-of <b>SiSU</b> offers great possibilities.
-<p>  <b>SiSU</b> is primarily for published works,
-which can take advantage of the citation system to reliably reference its
-documents. <b>SiSU</b> works well in a complementary manner with such collaborative
-technologies as Wikis, which can take advantage of and be used to discuss
-the substance of content prepared in <b>SiSU.</b>

-<p>  <b>SiSU</b> source documents are <i>plaintext</i> ( <i>UTF-8</i>
-)[^12] files
-<p>  All paragraphs are separated by an empty line.
-<p>  Markup is
-comprised of:
-<p>  * at the top of a document, the document header made up
-of semantic meta-data about the document and if desired additional processing
-instructions (such an instruction to automatically number headings from
-a particular level down)
-<p>  * followed by the prepared substantive text
-of which the most important single characteristic is the markup of different
-heading levels, which define the primary outline of the document structure.
-Markup of substantive text includes:
-<p>    * heading levels defines document
-structure<br>
-
-<p>    * text basic attributes, italics, bold etc.<br>
-
-<p>    * grouped text (objects), which are to be treated differently, such
-as code<br>
-   blocks or poems.<br>
-
-<p>    * footnotes/endnotes<br>
-
-<p>  * linked text and images
-<p>  * paragraph actions, such as indent, bulleted,
-numbered-lists, etc.
-<p>  Some interactive help on markup is available, by typing
-
-<p>sisu and selecting markup or sisu --help markup

-<h2><a name='sect44' href='#toc44'>Composite Documents Markup</a></h2>

-may be complete documents that could be generated independently, or they
-could be markup snippets, prepared so as to be easily available to be placed
-within another text. If the calling document is a master document (built
-from other documents), it should be named with the suffix <b>.ssm</b> Within this
-document you would provide information on the other documents that should
-be included within the text. These may be other documents that would be
-processed in a regular way, or markup bits prepared only for inclusion
-within a master document <b>.sst</b> regular markup file, or <b>.ssi</b> (insert/information)

-<pre>&lt;&lt; filename1.sst
-&lt;&lt; filename2.ssi

-<dd>documents are prepared as plain-text
-(utf-8) files with <b>SiSU</b> markup. They may make reference to and contain images
-(for example), which are stored in the directory beneath them _sisu/image.
-〔b¤SiSU <i>plaintext</i> markup files are of three types that may be distinguished
-by the file extension used: regular text .sst; master documents, composite
-documents that incorporate other text, which can be any regular text or
-text insert; and inserts the contents of which are like regular text except
-these are marked .ssi and are not processed.
-<p>  <b>SiSU</b> processing can be done

-<b>SiSU</b> markup in the <b>SiSU</b> manual.
-<p>  Note: Master documents may be prepared
-in a similar way to regular documents, and processing will occur normally

-with a document. A sisupod automatically bundles all associated files with
-the document that is turned into a pod.
-<p>  The structure of the sisupod is
-such that it may for example contain a single document and its associated
-images; a master document and its associated documents and anything else;
-or the zipped contents of a whole directory of prepared <b>SiSU</b> documents.
-

-<h2><a name='sect56' href='#toc56'>Organising Content - Directory Structure and Mapping</a></h2>
-
-<p>
- <b>SiSU</b> v3 has new options for the source directory tree, and output directory
-structures of which there are 3 alternatives.
-<p>
-<h2><a name='sect57' href='#toc57'>Document Source Directory</a></h2>
-
-<p>
- The document source directory is the directory in which sisu processing
-commands are given. It contains the sisu source files (.sst .ssm .ssi), or
-(for sisu v3 may contain) subdirectories with language codes which contain
-the sisu source files, so all English files would go in subdirectory en/,
-French in fr/, Spanish in es/ and so on. ISO 639-1 codes are used (as varied
-by po4a). A list of available languages (and possible sub-directory names)
-can be obtained with the command "sisu --help lang" The list of languages
-is limited to langagues supported by XeTeX polyglosia.
-<p>
-<h2><a name='sect58' href='#toc58'>General Directories</a></h2>
-
-<p>
-<br>
-<pre>% files stored at this level e.g. sisu_manual.sst or
-% for sisu v3 may be under language sub-directories
-% e.g.
- ./subject_name/en
- ./subject_name/fr
- ./subject_name/es
- ./subject_name/_sisu
- ./subject_name/_sisu/css
- ./subject_name/_sisu/image

-<h2><a name='sect59' href='#toc59'>Document Output Directory Structures</a></h2>
-
-<p>
-<h2><a name='sect60' href='#toc60'>Output Directory Root</a></h2>
-
-<p>  The output
-directory root can be set in the sisurc.yml file. Under the root, subdirectories
-are made for each directory in which a document set resides. If you have
-a directory named poems or conventions, that directory will be created
-under the output directory root and the output for all documents contained
-in the directory of a particular name will be generated to subdirectories
-beneath that directory (poem or conventions). A document will be placed
-in a subdirectory of the same name as the document with the filetype identifier
-stripped (.sst .ssm)
-<p>  The last part of a directory path, representing the
-sub-directory in which a document set resides, is the directory name that
-will be used for the output directory. This has implications for the organisation
-of document collections as it could make sense to place documents of a
-particular subject, or type within a directory identifying them. This grouping
-as suggested could be by subject (sales_law, english_literature); or just
-as conveniently by some other classification (X University). The mapping
-means it is also possible to place in the same output directory documents
-that are for organisational purposes kept separately, for example documents
-on a given subject of two different institutions may be kept in two different
-directories of the same name, under a directory named after each institution,
-and these would be output to the same output directory. Skins could be associated
-with each institution on a directory basis and resulting documents will
-take on the appropriate different appearance.
-<p>
-<h2><a name='sect61' href='#toc61'>Alternative Output Structures</a></h2>
-
-<p>
- There are 3 possibile output structures described as being, by language,
-by filetype or by filename, the selection is made in sisurc.yml

-<p>  2. through providing what you want as the

-<h2><a name='sect73' href='#toc73'>Sisu
-Search - Introduction</a></h2>
-
-<p>  <b>SiSU</b> output can easily and conveniently be indexed
-by a number of standalone indexing tools, such as Lucene, Hyperestraier.
-
-<p>  Because the document structure of sites created is clearly defined, and
-the text <i>object</i> citation system is available hypothetically at least, for
-all forms of output, it is possible to search the sql database, and either
-read results from that database, or just as simply map the results to the
-html output, which has richer text markup.
-<p>  In addition to this <b>SiSU</b> has
-the ability to populate a relational sql type database with documents at
-an object level, with objects numbers that are shared across different
-output types, which make them searchable with that degree of granularity.
-Basically, your match criteria is met by these documents and at these locations
-within each document, which can be viewed within the database directly
-or in various output formats.
-<p>
-<h2><a name='sect74' href='#toc74'>Sql</a></h2>
-
-<p>
-<h2><a name='sect75' href='#toc75'>Populating Sql Type Databases</a></h2>
-
-<p>  <b>SiSU</b> feeds
-sisu markupd documents into sql type databases <i>PostgreSQL</i> [^20] and/or <i>SQLite</i>
-[^21] database together with information related to document structure.
-<p>
- This is one of the more interesting output forms, as all the structural
-data of the documents are retained (though can be ignored by the user of
-the database should they so choose). All site texts/documents are (currently)
-streamed to four tables:
-<p>  * one containing semantic (and other) headers,
-including, title, author,   subject, (the<br>
-   .I Dublin Core.<br>
-   ..);<br>
-
-<p>  * another the substantive texts by individual "paragraph" (or object)
-- along   with structural information, each paragraph being identifiable
-by its<br>
-   paragraph number (if it has one which almost all of them do), and the<br>
-   substantive text of each paragraph quite naturally being searchable
-(both in<br>
-   formatted and clean text versions for searching); and<br>
-
-<p>  * a third containing endnotes cross-referenced back to the paragraph
-from   which they are referenced (both in formatted and clean text versions
-for<br>
-   searching).<br>
-
-<p>  * a fourth table with a one to one relation with the headers table contains
-  full text versions of output, eg. pdf, html, xml, and<br>
-   .I ascii.<br>
-
-<p>  There is of course the possibility to add further structures.
-<p>  At this
-level <b>SiSU</b> loads a relational database with documents chunked into objects,
-their smallest logical structurally constituent parts, as text objects,
-with their object citation number and all other structural information
-needed to construct the document. Text is stored (at this text object level)
-with and without elementary markup tagging, the stripped version being
-so as to facilitate ease of searching.
-<p>  Being able to search a relational
-database at an object level with the <b>SiSU</b> citation system is an effective
-way of locating content generated by <b>SiSU.</b> As individual text objects of
-a document stored (and indexed) together with object numbers, and all versions
-of the document have the same numbering, complex searches can be tailored
-to return just the locations of the search results relevant for all available
-output formats, with live links to the precise locations in the database
-or in html/xml documents; or, the structural information provided makes
-it possible to search the full contents of the database and have headings
-in which search content appears, or to search only headings etc. (as the
-<i>Dublin</i> Core is incorporated it is easy to make use of that as well).

-<p>  *
-sparse/minimal markup (clean utf-8 source texts). Documents are prepared
-in a single <i>UTF-8</i> file using a minimalistic mnemonic syntax. Typical literature,
-documents like "War and Peace" require almost no markup, and most of the
-headers are optional.
-<p>  * markup is easily readable/parsable by the human
-eye, (basic markup is simpler and more sparse than the most basic <i>HTML</i>
-) , [this may also be converted to <i>XML</i> representations of the same input/source
-document].
-<p>  * markup defines document structure (this may be done once
-in a header pattern-match description, or for heading levels individually);
-basic text attributes (bold, italics, underscore, strike-through etc.) as
-required; and semantic information related to the document (header information,
-extended beyond the Dublin core and easily further extended as required);
-the headers may also contain processing instructions. <b>SiSU</b> markup is primarily
-an abstraction of document structure and document metadata to permit taking
-advantage of the basic strengths of existing alternative practical standard
-ways of representing documents [be that browser viewing, paper publication,
-sql search etc.] (html, epub, xml, odf, latex, pdf, sql)
-<p>  * for output
-produces reasonably elegant output of established industry and institutionally
-accepted open standard formats.[3] takes advantage of the different strengths
-of various standard formats for representing documents, amongst the output
-formats currently supported are:
-<p>  * <i>HTML</i> - both as a single scrollable
-
-<p>text and a segmented document
-<p>  * <i>XHTML</i>
-<p>  * <i>EPUB</i>
-<p>  * <i>XML</i> - both in sax and
-
-<p>dom style xml structures for further development as required
-<p>  * <i>ODT</i> - Open
-Document Format text, the iso standard for document storage
-<p>  * <i>LaTeX</i> -
-
-<p>used to generate pdf
-<p>  * <i>PDF</i> (via <i>LaTeX</i> )
-<p>  * <i>SQL</i> - population of an sql
-database ( <i>PostgreSQL</i> or <i>SQLite</i> ) , (at the same object level that is used
-to cite text within a document)
-<p>  Also produces: concordance files; document
-content certificates (md5 or sha256 digests of headings, paragraphs, images
-etc.) and html manifests (and sitemaps of content). (b) takes advantage of
-the strengths implicit in these very different output types, (e.g. PDFs produced
-using typesetting of <i>LaTeX,</i> databases populated with documents at an individual
-object/paragraph level, making possible <i>granular</i> search (and related possibilities))
-
-<p>  * ensuring content can be cited in a meaningful way regardless of selected
-output format. Online publishing (and publishing in multiple document formats)
-lacks a useful way of citing text internally within documents (important
-to academics generally and to lawyers) as page numbers are meaningless
-across browsers and formats. sisu seeks to provide a common way of pinpoint
-the text within a document, (which can be utilized for citation and by
-search engines). The outputs share a common numbering system that is meaningful
-(to man and machine) across all digital outputs whether paper, screen,
-or database oriented, (pdf, <i>HTML,</i> <i>EPUB,</i> xml, sqlite, postgresql) , this
-numbering system can be used to reference content.
-<p>  * Granular search within
-documents. <i>SQL</i> databases are populated at an object level (roughly headings,
-paragraphs, verse, tables) and become searchable with that degree of granularity,
-the output information provides the object/paragraph numbers which are
-relevant across all generated outputs; it is also possible to look at just
-the matching paragraphs of the documents in the database; [output indexing
-also work well with search indexing tools like hyperestraier].
-<p>  * long
-term maintainability of document collections in a world of changing formats,
-having a very sparsely marked-up source document base. there is a considerable
-degree of future-proofing, output representations are "upgradeable", and
-new document formats may be added. e.g. addition of odf (open document text)
-module in 2006, epub in 2009 and in future html5 output sometime in future,
-
-<p>without modification of existing prepared texts
-<p>  * <i>SQL</i> search aside, documents
-are generated as required and static once generated.
-<p>  * documents produced
-are static files, and may be batch processed, this needs to be done only
-once but may be repeated for various reasons as desired (updated content,
-addition of new output formats, updated technology document presentations/representations)
-
-<p>  * document source ( <i>plaintext</i> utf-8) if shared on the net may be used
-
-<p>as input and processed locally to produce the different document outputs
-
-<p>  * document source may be bundled together (automatically) with associated
-documents (multiple language versions or master document with inclusions)
-and images and sent as a zip file called a sisupod, if shared on the net
-
-<p>these too may be processed locally to produce the desired document outputs
-
-<p>  * generated document outputs may automatically be posted to remote sites.
-
-<p>  * for basic document generation, the only software dependency is <b>Ruby,</b>
-and a few standard Unix tools (this covers <i>plaintext,</i> <i>HTML,</i> <i>EPUB,</i> <i>XML,</i>
-<i>ODF,</i> <i>LaTeX</i> ) . To use a database you of course need that, and to convert
-the <i>LaTeX</i> generated to pdf, a latex processor like tetex or texlive.
-<p>  *
-
-<p>as a developers tool it is flexible and extensible
-<p>  Syntax highlighting
-for <b>SiSU</b> markup is available for a number of text editors.
-<p>  <b>SiSU</b> is less
-about document layout than about finding a way with little markup to be
-able to construct an abstract representation of a document that makes it
-possible to produce multiple representations of it which may be rather
-different from each other and used for different purposes, whether layout
-and publishing, or search of content
-<p>  i.e. to be able to take advantage
-from this minimal preparation starting point of some of the strengths of
-rather different established ways of representing documents for different
-purposes, whether for search (relational database, or indexed flat files
-generated for that purpose whether of complete documents, or say of files
-made up of objects), online viewing (e.g. html, xml, pdf) , or paper publication
-(e.g. pdf) ...
-<p>  the solution arrived at is by extracting structural information
-about the document (about headings within the document) and by tracking
-objects (which are serialized and also given hash values) in the manner
-described. It makes possible representations that are quite different from
-those offered at present. For example objects could be saved individually
-and identified by their hashes, with an index of how the objects relate
-to each other to form a document.
-<p>
-<ol>
-<b>.</b><li>objects include: headings, paragraphs,
-verse, tables, images, but not footnotes/endnotes which are numbered separately
-and tied to the object from which they are referenced.
-<p>  </li><b>.</b><li>i.e. the HTML, PDF,
-EPUB, ODT outputs are each built individually and optimised for that form

-Features:
-#{@cX.cyan}(i)#{@cX.off} minimal markup requirement
-#{@cX.cyan}(ii)#{@cX.off} single file marked up for multiple outputs
-#{@cX.cyan}(iii)#{@cX.off} markup is simpler than html
-#{@cX.cyan}(iv)#{@cX.off} the simple syntax is mnemonic, influenced by mail/messaging/wiki markup practices
-#{@cX.cyan}(v)#{@cX.off} human readable, and easily writable
-#{@cX.cyan}(vi)#{@cX.off} multiple outputs include amongst others: html; pdf via LaTeX; (structured) XML; sql - currently PostgreSQL and sqlite; plaintext, (also texinfo)
-#{@cX.cyan}(vii)#{@cX.off} all text objects (headings and paragraphs) are numbered identically, for citation purposes, in all outputs (html, pdf, sql etc.)
-#{@cX.cyan}(viii)#{@cX.off} creates organised directory/file structure for output
-#{@cX.cyan}(ix)#{@cX.off} easily mapped with its clearly defined structure, with all text objects numbered, you know in advance where in each document output type, a bit of text will be found (eg. from an sql search, you know where to go to find the prepared html output or pdf etc.)... there is more
-#{@cX.cyan}(x)#{@cX.off} use of Dublin Core and other meta-tags to permit the addition of some semantic information on documents, and making easy integration of rdf/rss feeds etc.
-#{@cX.cyan}(xi)#{@cX.off} very easily skinnable, document appearance on a project/site wide, or document instance level easily controlled/changed
-#{@cX.cyan}(xii)#{@cX.off} in many cases a regular expression may be used (once in the document header) to define all or part of a documents structure obviating or reducing the need to provide structural markup within the document
-#{@cX.cyan}(xiii)#{@cX.off} is a batch processor for handling large document sets, ... though once generated they need not be re-generated, unless changes are made to the desired presentation of a particular output type
-#{@cX.cyan}(xiv)#{@cX.off} possible to pre-process, which permits the easy creation of standard form documents, and templates/term-sheets
-#{@cX.cyan}(xv)#{@cX.off} extremely modular, (thanks in no small part to Ruby) another output format required, write another module....
-#{@cX.cyan}(xvi)#{@cX.off} easy to update output formats (eg html, xhtml, latex/pdf produced can be updated in program and run against whole document set)
-#{@cX.cyan}(xvii)#{@cX.off} easy to add, modify, or have alternative syntax rules for input, should you need to
-#{@cX.cyan}(xviii)#{@cX.off} "Concordance" wordmap, consisting of all the words in a document and their (text object) locations within the text
-#{@cX.cyan}(xix)#{@cX.off} tied to revision control system, only code and marked up file need be backed up, to be sure of the much larger document set
-#{@cX.cyan}(xx)#{@cX.off} syntax highlighting files for markup, primarily (g)vim so far.

-SiSU was developed in relation to legal documents, and so is strong across a wide variety of texts (law, literature...), though weak on formulae/statistics, it does handle images. An assumption has been document sets that are to be preserved and maintained over time (also a result of the legal text origin). SiSU has been developed and used over a number of years, and the requirements to cover a wide range of documents have been thoroughly explored.

- #{@cX.ruby}-a#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces plaintext with Unix linefeeds. Without markup, (object numbers are omitted), has footnotes at end of each para‐ graph that contains them. Modifier options available: --footnotes (default) or --endnotes and for linefeeds --unix (default) or --msdos
-
- #{@cX.ruby}-b#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces xhtml/XML output for browser viewing (sax parsing)
-
- #{@cX.ruby}-C#{@cX.off} initialise shared output directory (config files such as css and dtd files are not updated if they already exist unless modifier is used) #{@cX.ruby}-C --init=site#{@cX.off} configure/initialise site more extensive than -C on its own, shared output directory files/force update, existing shared output config files such as css and dtd files are updated if this modifier is used. in a new markup document working directory should initialise the corresponding output directory, though SiSU will automatically do this, the first time it is run (for processing) in a given directory.
-
- #{@cX.ruby}-c#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} screen toggle ansi screen colour on or off depending on default set (unless -c flag is used: if sisurc colour default is set to ´true´, output to screen will be with colour, if sisurc colour default is set to ´false´ or is undefined screen output will be without colour)
-

-
- #{@cX.ruby}-F#{@cX.off} generate examples of (naive) cgi search form for sqlite and pgsql depends on your already having used sisu to populate an sqlite and/or pgsql database, (the sqlite version scans the output directories for existing sisu_sqlite databases, so it is first necessary to create them, before generating the search form) see -d -D and the database section below. If the optional parameter webrick is passed, the cgi examples created will be set up to use the default port set for use by the webrick server, (otherwise the port is left blank and the system setting used, usually 80). The samples are dumped in the present work directory which must be writable, (with screen instructions given that they be copied to the cgi-bin directory).
-
- #{@cX.ruby}-H#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces html (css version) (creates html (using css)), with url link suffixes (.html .pdf etc.) omitted ("Hide"). For web servers that are confireud so as not to require file extensions to locate and serve files. [behaviour switched see -h]
-
- #{@cX.ruby}-h#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces html (hardlinks i.e. with name suffixes in links/local urls). html, with internal document links that include the document suffix, ie whether it is .html or .pdf (required for browsing directly off a file system, and works with most web servers). [behaviour switched see -H]
-
- #{@cX.ruby}-I#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces texinfo file with its myriad of possibilities
-
- #{@cX.ruby}-L#{@cX.off} prints license information
-
- #{@cX.ruby}-M#{@cX.off} #{@cX.green}[filename/wildcard/url]#{@cX.off} maintenance mode, files created for processing are not deleted, and their locations are indicated (also see -V)
-
- #{@cX.ruby}-m#{@cX.off} #{@cX.green}[filename/wildcard/url]#{@cX.off} create (new)metaVerse (used in all subsequent processing). Produce a meta file, the first step in processing, and the file all subsequent processing utilize. (Should usually be run together with other commands to ensure that the lated version of markup source document is used, i.e. add -m flag to other flags required).
-
- #{@cX.ruby}-N#{@cX.off} #{@cX.green}[filename/wildcard/url]#{@cX.off} document content certificate as md5 digest tree of document produced (as digest.txt), the digest for the document, and digests for each object contained within the document (together with information on software versions that produced it). Try -mNV for verbose digest output to screen
-
- #{@cX.ruby}-n#{@cX.off} #{@cX.green}[filename/wildcard/url]#{@cX.off} skip meta-markup (building of "metaverse"), this skips the equivalent of -m
-
- #{@cX.ruby}-p#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces LaTeX pdf (portrait & landscape). Default paper size is set in config file, or document header, or provided with additional command line parameter, e.g. --papersize='a4' preset sizes include: 'A4', U.S. 'letter' and 'legal' and book sizes 'A5' and 'B5' (system defaults to A4).
-
- #{@cX.ruby}-q#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} quiet, less output to screen
-
- #{@cX.ruby}-r#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} copies sisu output files to remote host using scp (default). This requires that sisurc.yml has been provided with information on hostname and user name, and that you have your "keys" and ssh agent in place.
-
- #{@cX.ruby}-S#{@cX.off} #produces a sisupod, a zipped sisu directory of markup files including sisu markup source files and the directories local configuration file, images and skins. Note: this only includes the configuration files or skins contained in ./_sisu not those in ~/.sisu The resulting tar gzip file has a .zip suffix added to the markup source directory name. To tar and gzip individual files see the -Z [filename/wildcard] option. Note: (this option is tested only with zsh)
-
- #{@cX.ruby}-S#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces a sisupod a zipped sisu of the content assocated with the specified sisu markup documnt, i.e. including sisu markup source file, (and associated documents if a master file, or available in multilingual versions), together with related images and skin. The resulting zipped file has a .zip suffix added to the markup source file name by default, though a .ssp suffix is also recognised. The directory structure of the unzipped file is understood by sisu, and sisu commands can be run within it. SiSU commands can be run against a sisupod contained in a local directory, or provided as a url on a remote site. As there is a security issue with skins provided by other users, they are not applied unless the flag --trust or --trusted is added to the command instruction, it is recommended that file that are not your own are treated as untrusted. This provides a convenient way of packing documents files for sending Note: if you wish to send multiple files, it quickly becomes more space efficient to tar and gzip the sisu markup directory, (without the _sisu_processing subdirectory) rather than the individual files for sending). See the -S option without [filename/wildcard]
-
- #{@cX.ruby}-T#{@cX.off} #{@cX.green}[filename/wildcard (*.termsheet.rb)]#{@cX.off} standard form document builder, preprocessing feature
-
- #{@cX.ruby}-t#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces plaintext with Unix linefeeds. Without markup, (object numbers are omitted), has footnotes at end of each para‐ graph that contains them. Modifier options available: --footnotes (default) or --endnotes and for linefeeds --unix (default) or --msdos
-
- #{@cX.ruby}-U#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} prints url list/map for the available processing flags options and resulting files that could be requested, (can be used to get a list of processing options in relation to a file, together with information on the output that would be produced), -u provides url mapping for those flags requested for processing. The default assumes sisu_webrick is running and provides webrick url mappings where appropriate, but these can be switched to file system paths in sisurc.yml
-
- #{@cX.ruby}-u#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} provides url mapping of output files for the flags requested for processing, also see -U
-
- #{@cX.ruby}-V#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} on its own provides SiSU version and environment information (sisu --help env)
-
- #{@cX.ruby}-V#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} even more verbose than -v the -V flag provides some additional information, also see -M
-
- #{@cX.ruby}-v#{@cX.off} on its own, provides SiSU version information.
-
- #{@cX.ruby}-v#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} provides more verbose output of what is being built, where it is being built (and error messages if any), as with -u flag provides a url mapping of files created for each of the processing flag requests

-  #{@cX.cyan}Composite documents#{@cX.off}
-
-    It is possible to build a document by creating a master document that requires other documents. The documents required may complete documents that could be generated independently, or they could be markup snippets, prepared so as to be easily available to be placed within another text. If the calling document is a master document (built mainly from other documents), it should be named with the suffix #{@cX.blue}.ssm#{@cX.off} Within this document you would provide information on the other documents that should be included within the text. These may be other documents that would be processed in a regular way, or markup bits prepared only for inclusion within a master document #{@cX.blue}.sst#{@cX.off} regular markup file, or #{@cX.blue}.ssi#{@cX.off} (insert/information) A secondary file of the composite document is built prior to processing with the same prefix and the suffix #{@cX.blue}.ssm.sst#{@cX.off}

-
-  #{@cX.cyan}Composite documents - remote parts#{@cX.off}
-    Composite documents may be built from remote parts, by using the composite document syntax with a url. This makes sense using either sisu regular syntax (which is just a convenient way of marking up), or thlnk syntax, which also recognises remote urls, and permits hyperlinking ascii to the url location.
-
-  #{@cX.cyan}Remote documents#{@cX.off}
-    SiSU will download and process remote locations if a url is provided instead of a filename. [this at present works only for sisu markup files without images]

-    There are a number of files that control the appearance of a site or a document i.e.
-
-    #{@cX.blue}(i)#{@cX.off} files that control #{@cX.green}site-wide appearance#{@cX.off}:
-
-        #{@cX.green}defaults.rb#{@cX.off}  initial values used by program, not necessary to change
-
-        skins are placed in a configuration directory beneath the markup directory ./_sisu/skin/doc or in ~/.sisu/skin/doc
-        if a skin is also to be used for a directory or site wide presentations, rather than being called for a single document then a softlink is placed from ~/.sisu/skin/dir or ~/.sisu/skin/site respectively to the relevant skin within ~/.sisu/skin/doc
-
-        rules for skin loading are in #{@cX.green}sysenv.rb#{@cX.off}
-        the skin loading heuristics / hierarchy is currently as follows:
-
-          a. if there is a skin requested within a document, thent that skin is used
-            0~skin skin_lm (would load skin ~/.sisu/skin/doc/skin_lm.rb)
-
-          b. use it if there is a "dir" skin with the same name as the source directory "stub" i.e.
-            if working in a directory called /home/myhome/workdir/lm
-            then if ~/.sisu/skin/dir/skin_lm.rb were found it would be used and skin_lm.rb would be a softlink to the relevant skin in the document skin directory (where all the actual skins are kept)
-
-          x. [additionally though discouraged a special rule can be set up in sysenv  AddSkin.select (which could override b if desired)]
-
-        #{@cX.green}skin_site_#{@cX.off}#{@cX.cyan}[name of site skin in use]#{@cX.off}#{@cX.green}.rb#{@cX.off}  this file is called by skin.rb
-          if there are several such files, site appearance may be changed by
-          requesting the skin_site desired from skin.rb
-    and
-
-    #{@cX.blue}(ii)#{@cX.off} presentation maintenance:
-          if you have a body of documents the easiest way to give them a particular appearance/skin, is to associate that directory with a skin, all files in that directory take on the specified appearance, changing appearance of documents once directories are set up is as simple as copying the files from one directory to another (or renaming the directory); or associating the directory with a different skin.

-
-   #{@cX.green}Note on subdirectories for output documents#{@cX.off}
-   The last part of the name of the directory you choose to work from is used as the major sub-directory in which output files are placed,
-   i.e. if you are working in a directory called #{@cX.blue}#{@env.path.home}/ebook#{@cX.off}
-        the output files will be placed in a sub-directory named after the processed text within #{@cX.blue}#{@env.path.webserv}/ebook#{@cX.off}
-   ( Within this major sub-directory, a sub-directory is made with the name of each document processed, into which output files - html, pdf, xml, plaintext etc. are placed (texinfo being an exception at present) )
-
-    #{@cX.green}sisu -C#{@cX.off} [#{@cX.green}--init=site#{@cX.off}] configure/initialise shared output directory files initialize shared output directory (config files such as css and dtd files are not updated if they already exist unless modifier is used).  -C --init=site configure/initialise site more extensive than -C on its own, shared output directory files/force update, existing shared output config files such as css and dtd files  are updated if this modifier is used.  in a new markup document working directory should initialise the corresponding output directory, though SiSU will automatically do this, the first time it is run (for processing) in a given directory.

-   There are additional details, ... this should get you started.

-
-  the directory structure used by sisu is controlled by the configuration files #{@cX.blue}sisurc.yml#{@cX.off}
-
-   there are separate directories for the following:
-
-    (a) #{@cX.green}data directories#{@cX.off}
-      the directories in which you place the SiSU marked-up data files that are to be processed
-      there may be as many directories and files as you choose to have,
-      you are currently in:                                    #{@cX.blue}#{Dir.pwd}#{@cX.off}
-
-    (b) #{@cX.green}output directory#{@cX.off}
-      by default files in the data directory are output to
-      a sub-directory within the output directory (usually the web document directory), or to an sql database
-      of the same name as the stub or last portion of the data directory name
-      by way of example
-      you are currently in:                                    #{@cX.blue}#{Dir.pwd}#{@cX.off}
-      the document output directory is set to:                 #{@cX.blue}#{@env.path.webserv}#{@cX.off}
-      documents from your current directory will be placed in: #{@cX.blue}#{@env.path.output}#{@cX.off}
-
-      the final output is placed in subdirectories either as configured by default in the program or as modified by SiSU configuration files
-      subdirectories are created within the main output directory, based on the name of the data directory
-      subsubdirectories are created the sub-directory contained in the main output directory based on the name of the file
-      (subdirectories are created in this (output) sub-directory named after the data file)
-      for this reason it is a convention to give descriptive names to the data file.
-      The default output directory is #{@cX.green}~/sisu_www#{@cX.off}
-      The output directory is currently set to:
-        #{@cX.blue}#{@env.path.webserv}#{@cX.off}
-      Output files, are currently set to be produced in:
-        processed document output:           #{@cX.blue}#{@env.path.output}#{@cX.off}
-        a document in the current directory  #{@cX.blue}#{Dir.pwd}#{@cX.off}
-            will have its output placed in:  #{@cX.blue}#{@env.path.output}/#{@output_stub}#{@cX.off}
-
-      NB: the verbose flag v included in the generate command string, should
-      result in a list of output filenames together with their paths.
-      The flag U on its own (e.g. sisu -U gpl3.fsf.sst) should provide a list
-      of output files that could be generated together with their paths.
-
-    (c) #{@cX.green}configuration files#{@cX.off}
-       SiSU program defaults are set within the program, and may be adjusted in the yml file #{@cX.blue}sisurc.yml#{@cX.off} which is searched for in the following paths, which are prioritized as listed (the first one found is loaded):
-###
-       under the current SiSU markup data directory: #{@cX.blue}#{@env.path.pwd}/_sisu/sisurc.yml#{@cX.off}
-       under the home directory ~/.sisu:             #{@cX.blue}#{@env.path.home}/.sisu/sisurc.yml#{@cX.off}
-       in the "/etc" directory:                      #{@cX.blue}#{@env.path.etc}/sisurc.yml#{@cX.off}
-
-    (d) #{@cX.green}processing directories#{@cX.off}     sisu creates a number of processing directories,
-      where these should be located can be modified in #{@cX.green}~/.sisu/sisurc.yml#{@cX.off}
-      work directories include the following:
-          root working directory                               #{@cX.blue}#{@env.processing_path.processing}#{@cX.off}
-          metaverse       intermediate markup                  #{@cX.blue}#{@env.processing_path.dal}#{@cX.off}
-          tune html       (for special html/navigation pages)  #{@cX.blue}#{@env.processing_path.tune}#{@cX.off}
-          tex             for latex and pdf                    #{@cX.blue}#{@env.processing_path.tex}#{@cX.off}
-          texinfo         for texinfo and info files           #{@cX.blue}#{@env.processing_path.texi}#{@cX.off}
-
-      These files are usually used only for processing and removed. There is a maintenance flag to keep them.
-
-    (e) #{@cX.green}images#{@cX.off}
-      there are a number of categories of images,
-      NB the document markup directory is initialised by issuing the command
-        sisu -C --init=site
-      this creates the output sub-directory, and makes necessary image links, and
-      copies images specific to the markup directory if there are any.
-
-      general images for the sisu program that come with the package,
-      that are the defaults used by sisu, these are installed with the program
-
-      images that the author wishes to include within documents,
-      these should be placed in a sub-directory
-      within the current document markup directory called #{@cX.green}_sisu/image#{@cX.off}
-
-      if an instruction is given to process a remote document which contains
-      downloadable images, they are included in a sub-directory of the current
-      markup directory #{@cX.green}_sisu/sisu/image_external#{@cX.off} that is created
-      if necessary for the purpose.
-
-      finally skins may specify/indicate other image directories. see sisu --help skin
-      any site images required by the skin instruction must be copied in to the
-      site image directory (it may be necessary to do manual configuration depending
-      on what you are trying to achieve).

-These are not required, a header is quicker to prepare if a documents structure can be defined by matching words or a regular expression, see headers).
-
-@structure: PART; CHAPTER; SECTION; ARTICLE; none; none;
-
-structure can be defined by a match words or regular expression (the regular expression is assumed to start at the beginning of a line of text i.e. ^)
-
-The following heading or level (structuring) defaults are available (for use instead of or together with @structure: header):
-
-  A~  B~  C~  1~  2~  3~
-
-Heading tags take either of the forms above, ranging from 1-6
-
-They appear at the beginning of the line on which a heading appears,
-the number indicates the level of the heading with level 1 being a title,
-
-segments (in html output) are by default created on level 4
-(segmented text is split/segmented on level 4, and
-assigned a file name automatically according to the title number,
-unless you explicitly specify otherwise)
-
-A~ Document Title
-
-B~ Document Subtitle whatever it is
-
-C~ Part
-
-1~ Chapter
-
-2~ Heading
-
-3~ sub-heading
-
-Normal text would follow each heading level as appropriate, though it is most usual to start with ordinary writing beneath level 4 as it is at this level that segments are created.
-
-Automatic numbering of paragraphs is usually set to start at level 4 trough level 6 and takes the form 1. then 1.1 then 1.1.1 this being given as a Header tag 0~ There may be up to 6 levels in a document,
-
-If auto-numbering is on, then for html output the segments created  (on level 4 headings) are automatically assigned the name of the title number.
-However, you may indicate an alternative set of key/title words, with one of the following instructions:
-4~filename This is a Section or Subject Heading
-
-If there is a strictly discernable word appearing at the beginning of the line in a document that identifies the level,
-the words can be used to identify the levels in a header tag:
-0~toc Part; Chapter; Section; Article; none; none
-instead of providing individual heading tags
-
-sisu structure, notation, A,B,C,1,2,3
-
- SiSU has in effect two sets of levels to be considered
-
- A-C pre-ordinary paragraphs /pre-substantive text, and
-
- 1-3 levels which are followed by ordinary text.
-
- This may be conceptualised as levels A,B,C, 1,2,3, and using such letter number notation, in effect:
-
- A must exist, optional B and C follow in the sequence
-
- 1 must exist, optional 2 and 3 follow in the sequence
-
- i.e. there are two independent heading level sequences A,B,C and 1,2,3 or using the standard notation 1,2,3 and 4,5,6
-
-on the positive side: (a) the A,B,C,1,2,3 alternative makes explicit an aspect of structuring documents in SiSU that is not otherwise obvious to the newcomer (though it appears more complicated, is more in your face and likely to be understood fairly quickly); (b) the substantive text follows levels 1,2,3 and it is 'nice' to do most work in those levels

- Multi-language Document File Naming and Directory Mapping
-
- A list of language codes and languages that may be available for most output formats. These are for the most part ISO 639/1 and where there is a departure it follows those made by po4a, and the languages supported will be limited (at this time) to those supported by polyglossia. (SiSU markup text is stored in Unicode so some output formats are served by this, for example, html and sql had no problem with Chinese, pdfs would be a problem as this is not (yet?) suported by xetex and polyglossia. SiSU parses left to right and would have problems with right to left languages.)
-
- If the same document exists in different language versions, a directory structure, or a filenaming convention may be followed. Using Spannish as the sample language code (es) [filename]~[language code].sst
-
- The simplest now is to place each document in a sub-directory which has the language code as a name, if this convention is used it is preferable that all files are placed by language in the appropriate language sub-directory ... e.g.
-   ./en/filename.sst
-   ./es/filename.sst
-
- Alternatively files may all be placed in the same directory with the language and named using a tilde and the language code as shown:
-  filename~es.sst
-
-  within sisurc.yml under the heading
-    default:
-      language file: [at 1, 2 or 3]
-
-  determines the output filenaming convention used, as follows:
-
-    (1) [output directory path]/filename/es.index.html
-
-    (2) [output directory path]/filename/index.es.html
-
-    (3) [output directory path]/filename/index.html.es (which Apache for example can be configured to use to automatically serve each users preference)
-
-    filename~fr.sst
-    filename~de.sst
-
-  etc. would be placed in the same directory using the same convention as indeed would:
-    filename.sst
-  using the default convention mapping convention.
-
-  Selecting this form of filename will overide other language settings including the language header within a document.

-(1) Footnote/endnotes tags take a number of possible forms, the simplest being to embed an endnote within your text~{ this would appear as an endnote, and would have an automatically assigned number }~ Embedded endnotes~{this is an endnote}~ and at the end of the paragraph~{* an asterisk marked note }~ writing the endnote:~{another endnote}~

-#{@cX.ruby}All you need to know about endnotes appears above this line...#{@cX.off} apart from the fact that you cannot mix endnote markup styles
-
-(2) The other ways of inserting an endnote involve placing a tag within the text as to where the endnote reference number should appear like so~^ and at the end of the paragraph writing the endnote:~^
-
-^~ like so, this is an endnote
-
-^~ another endnote

-
-  Presumably if you are reading this interactively you have a copy of SiSU already installed, nevertheless here are a few notes.
-
-  SiSU does require setup, the executable file #{@cX.blue}sisu#{@cX.off} is placed in #{@cX.blue}#{Config::CONFIG['bindir']}#{@cX.off} or #{@cX.blue}#{Config::CONFIG['sitelibdir']}#{@cX.off} and the library files, in #{@cX.blue}#{Config::CONFIG['rubylibdir']}/#{SiSU_lib}#{@cX.off}
- or in #{@cX.blue}#{Config::CONFIG['sitelibdir']}/#{SiSU_lib}#{@cX.off}
-
-  SiSU comes with a number of installers, including #{@cX.blue}setup.rb#{@cX.off}, #{@cX.blue}install#{@cX.off} and a #{@cX.blue}Rantfile#{@cX.off} if rant is installed on your system, you may need to be root to install sisu on your system. After unpacking the tarball, in the top directory of the tarball which contains the named files type, one of:
-      sudo ./sisu-install base
-      sudo ./sisu-install setup
-    if that does not work try
-      sudo ruby ./sisu-install setup
-    if rant is installed on your system you may instead run:
-      sudo rant base
-
-    for further options:
-      ./sisu-install -T
-
-  SiSU is pre-packaged for some GNU/Linux distributions such as Debian.

-
-    sisu --sqlite --createdb         creates database where no database existed before
-    sisu --sqlite --create           creates database tables where no database tables existed before
-    sisu --sqlite --dropall          destroys database (including all its content)!!
-    sisu --sqlite --recreate         destroys existing database and builds a new empty database structure
-
-    sisu --sqlite --import [filename/wildcard]   populates database with the contents of the file
-    sisu --sqlite --update [filename/wildcard]   updates file contents in database
-
-    sisu --sample-search-form --webserv=webrick    builds a cgi web search frontend for the database created
-

-    current db set:   #{@cX.blue}#{@db.psql.db}#{@cX.off}

-
-  Note on databases built
-   By default, [unless otherwise specified] databases are built on a directory basis, from collections of documents within that directory.
-   The name of the directory you choose to work from is used as the database name,
-   i.e. if you are working in a directory called #{@cX.blue}#{@env.path.home}/ebook#{@cX.off} the database #{@cX.blue}#{Db[:name_prefix]}ebook#{@cX.off} is used. [otherwise a manual mapping for the collection is necessary]

-
-  NOTE: The examples that follow assume that sisu output is placed in the directory
-  /home/ralph/sisu_www
-
- (A)  to generate the index
-   within the webserver directory to be indexed:
-      #{@cX.orange}estcmd gather -sd [index name] [directory path to index]#{@cX.off}
-   the following are examples that will need to be tailored according to your needs:
-     #{@cX.green}
-     cd #{@env.path.webserv}
-     estcmd gather -sd casket #{@env.path.webserv}
-     #{@cX.off}
-     you may use the 'find' command together with 'egrep' to limit
-     indexing to particular document collection directories within
-     the web server directory:#{@cX.green}
-
-     find /home/ralph/sisu_www -type f | egrep '#{@env.path.output}/.+?\.html$' |estcmd gather -sd casket - #{@cX.off}
-
-     check which directories in the webserver/output directory #{@cX.green}#{@env.path.webserv}#{@cX.off}
-     you wish to include in the search index, these appear to be:
-
-     #{@env.path.webserv}/#{@cX.green}#{out_dir}#{@cX.off}
-
-     as sisu duplicates output in multiple file formats,
-     it it is probably preferable to limit the estraier index
-     to html output, and as it may also be desirable to
-     exclude files 'doc.html' and 'concordance.html', as these
-     duplicate information held in other html output e.g. #{@cX.green}
-
-     find /home/ralph/sisu_www -type f | egrep '/sisu_www/(sisu|bookmarks)/.+?\.html$' | egrep -v '(doc|concordance)\.html$' |estcmd gather -sd casket - #{@cX.off}
-
-     from your current document preparation/markup directory, you would construct a rune along the following lines: #{@cX.green}
-
-     find /home/ralph/sisu_www -type f | egrep '#{@env.path.webserv}/([specify first directory for inclusion]|[specify second directory for inclusion]|[another directory for inclusion? ...])/.+?\.html$' | egrep -v '(doc|concordance)\.html$' |estcmd gather -sd #{@env.path.webserv}/casket - #{@cX.off}
-
- (B) to set up the search form
-   (i) copy #{@cX.green}estseek.cgi#{@cX.off} to your cgi directory and set file permissions to 755: #{@cX.green}
-
-     sudo cp -vi /usr/lib/estraier/estseek.cgi /usr/lib/cgi-bin
-     sudo chmod -v 755 /usr/lib/cgi-bin/estseek.cgi
-     sudo cp -v /usr/share/hyperestraier/estseek.* /usr/lib/cgi-bin #{@cX.off}
-     [see estraier documentation for paths]
-
-   (ii) edit #{@cX.green}estseek.conf#{@cX.off}, with attention to the lines starting 'indexname:' and 'replace:': #{@cX.green}
-
-     indexname: #{@env.path.webserv}/casket
-     replace: ^file://#{@env.path.webserv}{{!}}#{@env.url.webserv_host_base}
-     replace: /index\.html?${{!}}/ #{@cX.off}
-
- (C) to test using webrick, start webrick: #{@cX.green}
-     sisu -W #{@cX.off}
-
-   and try open the url: #{@cX.blue}
-     #{@env.url.webserv_host_base}/cgi-bin/estseek.cgi #{@cX.off}

-Features:
-#{@cX.cyan}(i)#{@cX.off} minimal markup requirement
-#{@cX.cyan}(ii)#{@cX.off} single file marked up for multiple outputs
-#{@cX.cyan}(iii)#{@cX.off} markup is simpler than html
-#{@cX.cyan}(iv)#{@cX.off} the simple syntax is mnemonic, influenced by mail/messaging/wiki markup practices
-#{@cX.cyan}(v)#{@cX.off} human readable, and easily writable
-#{@cX.cyan}(vi)#{@cX.off} multiple outputs include amongst others: html; pdf via LaTeX; (structured) XML; sql - currently PostgreSQL and sqlite; plaintext, (also texinfo)
-#{@cX.cyan}(vii)#{@cX.off} all text objects (headings and paragraphs) are numbered identically, for citation purposes, in all outputs (html, pdf, sql etc.)
-#{@cX.cyan}(viii)#{@cX.off} creates organised directory/file structure for output
-#{@cX.cyan}(ix)#{@cX.off} easily mapped with its clearly defined structure, with all text objects numbered, you know in advance where in each document output type, a bit of text will be found (eg. from an sql search, you know where to go to find the prepared html output or pdf etc.)... there is more
-#{@cX.cyan}(x)#{@cX.off} use of Dublin Core and other meta-tags to permit the addition of some semantic information on documents, and making easy integration of rdf/rss feeds etc.
-#{@cX.cyan}(xi)#{@cX.off} very easily skinnable, document appearance on a project/site wide, or document instance level easily controlled/changed
-#{@cX.cyan}(xii)#{@cX.off} in many cases a regular expression may be used (once in the document header) to define all or part of a documents structure obviating or reducing the need to provide structural markup within the document
-#{@cX.cyan}(xiii)#{@cX.off} is a batch processor for handling large document sets, ... though once generated they need not be re-generated, unless changes are made to the desired presentation of a particular output type
-#{@cX.cyan}(xiv)#{@cX.off} possible to pre-process, which permits the easy creation of standard form documents, and templates/term-sheets
-#{@cX.cyan}(xv)#{@cX.off} extremely modular, (thanks in no small part to Ruby) another output format required, write another module....
-#{@cX.cyan}(xvi)#{@cX.off} easy to update output formats (eg html, xhtml, latex/pdf produced can be updated in program and run against whole document set)
-#{@cX.cyan}(xvii)#{@cX.off} easy to add, modify, or have alternative syntax rules for input, should you need to
-#{@cX.cyan}(xviii)#{@cX.off} "Concordance" wordmap, consisting of all the words in a document and their (text object) locations within the text
-#{@cX.cyan}(xix)#{@cX.off} tied to revision control system, only code and marked up file need be backed up, to be sure of the much larger document set
-#{@cX.cyan}(xx)#{@cX.off} syntax highlighting files for markup, primarily (g)vim so far.

-SiSU was developed in relation to legal documents, and so is strong across a wide variety of texts (law, literature...), though weak on formulae/statistics, it does handle images. An assumption has been document sets that are to be preserved and maintained over time (also a result of the legal text origin). SiSU has been developed and used over a number of years, and the requirements to cover a wide range of documents have been thoroughly explored.

-
- #{@cX.ruby}-F#{@cX.off} generate examples of (naive) cgi search form for sqlite and pgsql depends on your already having used sisu to populate an sqlite and/or pgsql database, (the sqlite version scans the output directories for existing sisu_sqlite databases, so it is first necessary to create them, before generating the search form) see -d -D and the database section below. If the optional parameter webrick is passed, the cgi examples created will be set up to use the default port set for use by the webrick server, (otherwise the port is left blank and the system setting used, usually 80). The samples are dumped in the present work directory which must be writable, (with screen instructions given that they be copied to the cgi-bin directory).
-
- #{@cX.ruby}-H#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces html (css version) (creates html (using css)), with url link suffixes (.html .pdf etc.) omitted ("Hide"). For web servers that are confireud so as not to require file extensions to locate and serve files. [behaviour switched see -h]
-
- #{@cX.ruby}-h#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces html (hardlinks i.e. with name suffixes in links/local urls). html, with internal document links that include the document suffix, ie whether it is .html or .pdf (required for browsing directly off a file system, and works with most web servers). [behaviour switched see -H]
-
- #{@cX.ruby}-I#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces texinfo file with its myriad of possibilities
-
- #{@cX.ruby}-L#{@cX.off} prints license information
-
- #{@cX.ruby}-M#{@cX.off} #{@cX.green}[filename/wildcard/url]#{@cX.off} maintenance mode, files created for processing are not deleted, and their locations are indicated (also see -V)
-
- #{@cX.ruby}-m#{@cX.off} #{@cX.green}[filename/wildcard/url]#{@cX.off} create (new)metaVerse (used in all subsequent processing). Produce a meta file, the first step in processing, and the file all subsequent processing utilize. (Should usually be run together with other commands to ensure that the lated version of markup source document is used, i.e. add -m flag to other flags required).
-
- #{@cX.ruby}-N#{@cX.off} #{@cX.green}[filename/wildcard/url]#{@cX.off} document content certificate as md5 digest tree of document produced (as digest.txt), the digest for the document, and digests for each object contained within the document (together with information on software versions that produced it). Try -mNV for verbose digest output to screen
-
- #{@cX.ruby}-n#{@cX.off} #{@cX.green}[filename/wildcard/url]#{@cX.off} skip meta-markup (building of "metaverse"), this skips the equivalent of -m
-
- #{@cX.ruby}-p#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces LaTeX pdf (portrait & landscape). Default paper size is set in config file, or document header, or provided with additional command line parameter, e.g. --papersize='a4' preset sizes include: 'A4', U.S. 'letter' and 'legal' and book sizes 'A5' and 'B5' (system defaults to A4).
-
- #{@cX.ruby}-q#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} quiet, less output to screen
-
- #{@cX.ruby}-r#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} copies sisu output files to remote host using scp (default). This requires that sisurc.yml has been provided with information on hostname and user name, and that you have your "keys" and ssh agent in place.
-
- #{@cX.ruby}-S#{@cX.off} #produces a sisupod, a zipped sisu directory of markup files including sisu markup source files and the directories local configuration file, images and skins. Note: this only includes the configuration files or skins contained in ./_sisu not those in ~/.sisu The resulting tar gzip file has a .zip suffix added to the markup source directory name. To tar and gzip individual files see the -Z [filename/wildcard] option. Note: (this option is tested only with zsh)
-
- #{@cX.ruby}-S#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces a sisupod a zipped sisu of the content assocated with the specified sisu markup documnt, i.e. including sisu markup source file, (and associated documents if a master file, or available in multilingual versions), together with related images and skin. The resulting zipped file has a .zip suffix added to the markup source file name by default, though a .ssp suffix is also recognised. The directory structure of the unzipped file is understood by sisu, and sisu commands can be run within it. SiSU commands can be run against a sisupod contained in a local directory, or provided as a url on a remote site. As there is a security issue with skins provided by other users, they are not applied unless the flag --trust or --trusted is added to the command instruction, it is recommended that file that are not your own are treated as untrusted. This provides a convenient way of packing documents files for sending Note: if you wish to send multiple files, it quickly becomes more space efficient to tar and gzip the sisu markup directory, (without the _sisu_processing subdirectory) rather than the individual files for sending). See the -S option without [filename/wildcard]

-
- #{@cX.ruby}-U#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} prints url list/map for the available processing flags options and resulting files that could be requested, (can be used to get a list of processing options in relation to a file, together with information on the output that would be produced), -u provides url mapping for those flags requested for processing. The default assumes sisu_webrick is running and provides webrick url mappings where appropriate, but these can be switched to file system paths in sisurc.yml
-
- #{@cX.ruby}-u#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} provides url mapping of output files for the flags requested for processing, also see -U

-  #{@cX.cyan}Composite documents#{@cX.off}
-
-    It is possible to build a document by creating a master document that requires other documents. The documents required may complete documents that could be generated independently, or they could be markup snippets, prepared so as to be easily available to be placed within another text. If the calling document is a master document (built mainly from other documents), it should be named with the suffix #{@cX.blue}.ssm#{@cX.off} Within this document you would provide information on the other documents that should be included within the text. These may be other documents that would be processed in a regular way, or markup bits prepared only for inclusion within a master document #{@cX.blue}.sst#{@cX.off} regular markup file, or #{@cX.blue}.ssi#{@cX.off} (insert/information) A secondary file of the composite document is built prior to processing with the same prefix and the suffix #{@cX.blue}.ssm.sst#{@cX.off}

-
-  #{@cX.cyan}Composite documents - remote parts#{@cX.off}
-    Composite documents may be built from remote parts, by using the composite document syntax with a url. This makes sense using either sisu regular syntax (which is just a convenient way of marking up), or thlnk syntax, which also recognises remote urls, and permits hyperlinking ascii to the url location.
-
-  #{@cX.cyan}Remote documents#{@cX.off}
-    SiSU will download and process remote locations if a url is provided instead of a filename. [this at present works only for sisu markup files without images]

-    There are a number of files that control the appearance of a site or a document i.e.
-
-    #{@cX.blue}(i)#{@cX.off} files that control #{@cX.green}site-wide appearance#{@cX.off}:
-
-        #{@cX.green}defaults.rb#{@cX.off}  initial values used by program, not necessary to change
-
-        skins are placed in a configuration directory beneath the markup directory ./_sisu/skin/doc or in ~/.sisu/skin/doc
-        if a skin is also to be used for a directory or site wide presentations, rather than being called for a single document then a softlink is placed from ~/.sisu/skin/dir or ~/.sisu/skin/site respectively to the relevant skin within ~/.sisu/skin/doc
-
-        rules for skin loading are in #{@cX.green}sysenv.rb#{@cX.off}
-        the skin loading heuristics / hierarchy is currently as follows:
-
-          a. if there is a skin requested within a document, thent that skin is used
-            0~skin skin_lm (would load skin ~/.sisu/skin/doc/skin_lm.rb)
-
-          b. use it if there is a "dir" skin with the same name as the source directory "stub" i.e.
-            if working in a directory called /home/myhome/workdir/lm
-            then if ~/.sisu/skin/dir/skin_lm.rb were found it would be used and skin_lm.rb would be a softlink to the relevant skin in the document skin directory (where all the actual skins are kept)
-
-          x. [additionally though discouraged a special rule can be set up in sysenv  AddSkin.select (which could override b if desired)]
-
-        #{@cX.green}skin_site_#{@cX.off}#{@cX.cyan}[name of site skin in use]#{@cX.off}#{@cX.green}.rb#{@cX.off}  this file is called by skin.rb
-          if there are several such files, site appearance may be changed by
-          requesting the skin_site desired from skin.rb
-    and
-
-    #{@cX.blue}(ii)#{@cX.off} presentation maintenance:
-          if you have a body of documents the easiest way to give them a particular appearance/skin, is to associate that directory with a skin, all files in that directory take on the specified appearance, changing appearance of documents once directories are set up is as simple as copying the files from one directory to another (or renaming the directory); or associating the directory with a different skin.

-
-   #{@cX.green}Note on subdirectories for output documents#{@cX.off}
-   The last part of the name of the directory you choose to work from is used as the major sub-directory in which output files are placed,
-   i.e. if you are working in a directory called #{@cX.blue}#{@env.path.home}/ebook#{@cX.off}
-        the output files will be placed in a sub-directory named after the processed text within #{@cX.blue}#{@env.path.webserv}/ebook#{@cX.off}
-   ( Within this major sub-directory, a sub-directory is made with the name of each document processed, into which output files - html, pdf, xml, plaintext etc. are placed (texinfo being an exception at present) )
-
-    #{@cX.green}sisu -C#{@cX.off} [#{@cX.green}--init=site#{@cX.off}] configure/initialise shared output directory files initialize shared output directory (config files such as css and dtd files are not updated if they already exist unless modifier is used).  -C --init=site configure/initialise site more extensive than -C on its own, shared output directory files/force update, existing shared output config files such as css and dtd files  are updated if this modifier is used.  in a new markup document working directory should initialise the corresponding output directory, though SiSU will automatically do this, the first time it is run (for processing) in a given directory.

-
-  the directory structure used by sisu is controlled by the configuration files #{@cX.blue}sisurc.yml#{@cX.off}
-
-   there are separate directories for the following:
-
-    (a) #{@cX.green}data directories#{@cX.off}
-      the directories in which you place the SiSU marked-up data files that are to be processed
-      there may be as many directories and files as you choose to have,
-      you are currently in:                                    #{@cX.blue}#{Dir.pwd}#{@cX.off}
-
-    (b) #{@cX.green}output directory#{@cX.off}
-      by default files in the data directory are output to
-      a sub-directory within the output directory (usually the web document directory), or to an sql database
-      of the same name as the stub or last portion of the data directory name
-      by way of example
-      you are currently in:                                    #{@cX.blue}#{Dir.pwd}#{@cX.off}
-      the document output directory is set to:                 #{@cX.blue}#{@env.path.webserv}#{@cX.off}
-      documents from your current directory will be placed in: #{@cX.blue}#{@env.path.output}#{@cX.off}
-
-      the final output is placed in subdirectories either as configured by default in the program or as modified by SiSU configuration files
-      subdirectories are created within the main output directory, based on the name of the data directory
-      subsubdirectories are created the sub-directory contained in the main output directory based on the name of the file
-      (subdirectories are created in this (output) sub-directory named after the data file)
-      for this reason it is a convention to give descriptive names to the data file.
-      The default output directory is #{@cX.green}~/sisu_www#{@cX.off}
-      The output directory is currently set to:
-        #{@cX.blue}#{@env.path.webserv}#{@cX.off}
-      Output files, are currently set to be produced in:
-        processed document output:           #{@cX.blue}#{@env.path.output}#{@cX.off}
-        a document in the current directory  #{@cX.blue}#{Dir.pwd}#{@cX.off}
-            will have its output placed in:  #{@cX.blue}#{@env.path.output}/#{@output_stub}#{@cX.off}
-
-      NB: the verbose flag v included in the generate command string, should
-      result in a list of output filenames together with their paths.
-      The flag U on its own (e.g. sisu -U gpl3.fsf.sst) should provide a list
-      of output files that could be generated together with their paths.
-
-    (c) #{@cX.green}configuration files#{@cX.off}
-       SiSU program defaults are set within the program, and may be adjusted in the yml file #{@cX.blue}sisurc.yml#{@cX.off} which is searched for in the following paths, which are prioritized as listed (the first one found is loaded):
-###
-       under the current SiSU markup data directory: #{@cX.blue}#{@env.path.pwd}/_sisu/sisurc.yml#{@cX.off}
-       under the home directory ~/.sisu:             #{@cX.blue}#{@env.path.home}/.sisu/sisurc.yml#{@cX.off}
-       in the "/etc" directory:                      #{@cX.blue}#{@env.path.etc}/sisurc.yml#{@cX.off}
-
-    (d) #{@cX.green}processing directories#{@cX.off}     sisu creates a number of processing directories,
-      where these should be located can be modified in #{@cX.green}~/.sisu/sisurc.yml#{@cX.off}
-      work directories include the following:
-          root working directory                               #{@cX.blue}#{@env.processing_path.processing}#{@cX.off}
-          metaverse       intermediate markup                  #{@cX.blue}#{@env.processing_path.dal}#{@cX.off}
-          tune html       (for special html/navigation pages)  #{@cX.blue}#{@env.processing_path.tune}#{@cX.off}
-          tex             for latex and pdf                    #{@cX.blue}#{@env.processing_path.tex}#{@cX.off}
-          texinfo         for texinfo and info files           #{@cX.blue}#{@env.processing_path.texi}#{@cX.off}
-
-      These files are usually used only for processing and removed. There is a maintenance flag to keep them.
-
-    (e) #{@cX.green}images#{@cX.off}
-      there are a number of categories of images,
-      NB the document markup directory is initialised by issuing the command
-        sisu -C --init=site
-      this creates the output sub-directory, and makes necessary image links, and
-      copies images specific to the markup directory if there are any.
-
-      general images for the sisu program that come with the package,
-      that are the defaults used by sisu, these are installed with the program
-
-      images that the author wishes to include within documents,
-      these should be placed in a sub-directory
-      within the current document markup directory called #{@cX.green}_sisu/image#{@cX.off}
-
-      if an instruction is given to process a remote document which contains
-      downloadable images, they are included in a sub-directory of the current
-      markup directory #{@cX.green}_sisu/sisu/image_external#{@cX.off} that is created
-      if necessary for the purpose.
-
-      finally skins may specify/indicate other image directories. see sisu --help skin
-      any site images required by the skin instruction must be copied in to the
-      site image directory (it may be necessary to do manual configuration depending
-      on what you are trying to achieve).

-These are not required, a header is quicker to prepare if a documents structure can be defined by matching words or a regular expression, see headers).
-
-@structure: PART; CHAPTER; SECTION; ARTICLE; none; none;
-
-structure can be defined by a match words or regular expression (the regular expression is assumed to start at the beginning of a line of text i.e. ^)
-
-The following heading or level (structuring) defaults are available (for use instead of or together with @structure: header):
-
-  A~  B~  C~  1~  2~  3~
-
-Heading tags take either of the forms above, ranging from 1-6
-
-They appear at the beginning of the line on which a heading appears,
-the number indicates the level of the heading with level 1 being a title,
-
-segments (in html output) are by default created on level 4
-(segmented text is split/segmented on level 4, and
-assigned a file name automatically according to the title number,
-unless you explicitly specify otherwise)
-
-A~ Document Title
-
-B~ Document Subtitle whatever it is
-
-C~ Part
-
-1~ Chapter
-
-2~ Heading
-
-3~ sub-heading
-
-Normal text would follow each heading level as appropriate, though it is most usual to start with ordinary writing beneath level 4 as it is at this level that segments are created.
-
-Automatic numbering of paragraphs is usually set to start at level 4 trough level 6 and takes the form 1. then 1.1 then 1.1.1 this being given as a Header tag 0~ There may be up to 6 levels in a document,
-
-If auto-numbering is on, then for html output the segments created  (on level 4 headings) are automatically assigned the name of the title number.
-However, you may indicate an alternative set of key/title words, with one of the following instructions:
-4~filename This is a Section or Subject Heading
-
-If there is a strictly discernable word appearing at the beginning of the line in a document that identifies the level,
-the words can be used to identify the levels in a header tag:
-0~toc Part; Chapter; Section; Article; none; none
-instead of providing individual heading tags
-
-sisu structure, notation, A,B,C,1,2,3
-
- SiSU has in effect two sets of levels to be considered
-
- A-C pre-ordinary paragraphs /pre-substantive text, and
-
- 1-3 levels which are followed by ordinary text.
-
- This may be conceptualised as levels A,B,C, 1,2,3, and using such letter number notation, in effect:
-
- A must exist, optional B and C follow in the sequence
-
- 1 must exist, optional 2 and 3 follow in the sequence
-
- i.e. there are two independent heading level sequences A,B,C and 1,2,3 or using the standard notation 1,2,3 and 4,5,6
-
-on the positive side: (a) the A,B,C,1,2,3 alternative makes explicit an aspect of structuring documents in SiSU that is not otherwise obvious to the newcomer (though it appears more complicated, is more in your face and likely to be understood fairly quickly); (b) the substantive text follows levels 1,2,3 and it is 'nice' to do most work in those levels

- Multi-language Document File Naming and Directory Mapping
-
- A list of language codes and languages that may be available for most output formats. These are for the most part ISO 639/1 and where there is a departure it follows those made by po4a, and the languages supported will be limited (at this time) to those supported by polyglossia. (SiSU markup text is stored in Unicode so some output formats are served by this, for example, html and sql had no problem with Chinese, pdfs would be a problem as this is not (yet?) suported by xetex and polyglossia. SiSU parses left to right and would have problems with right to left languages.)
-
- If the same document exists in different language versions, a directory structure, or a filenaming convention may be followed. Using Spannish as the sample language code (es) [filename]~[language code].sst
-
- The simplest now is to place each document in a sub-directory which has the language code as a name, if this convention is used it is preferable that all files are placed by language in the appropriate language sub-directory ... e.g.
-   ./en/filename.sst
-   ./es/filename.sst
-
- Alternatively files may all be placed in the same directory with the language and named using a tilde and the language code as shown:
-  filename~es.sst
-
-  within sisurc.yml under the heading
-    default:
-      language file: [at 1, 2 or 3]
-
-  determines the output filenaming convention used, as follows:
-
-    (1) [output directory path]/filename/es.index.html
-
-    (2) [output directory path]/filename/index.es.html
-
-    (3) [output directory path]/filename/index.html.es (which Apache for example can be configured to use to automatically serve each users preference)
-
-    filename~fr.sst
-    filename~de.sst
-
-  etc. would be placed in the same directory using the same convention as indeed would:
-    filename.sst
-  using the default convention mapping convention.
-
-  Selecting this form of filename will overide other language settings including the language header within a document.

-(1) Footnote/endnotes tags take a number of possible forms, the simplest being to embed an endnote within your text~{ this would appear as an endnote, and would have an automatically assigned number }~ Embedded endnotes~{this is an endnote}~ and at the end of the paragraph~{* an asterisk marked note }~ writing the endnote:~{another endnote}~

-^~ like so, this is an endnote

-
-  Presumably if you are reading this interactively you have a copy of SiSU already installed, nevertheless here are a few notes.
-
-  SiSU does require setup, the executable file #{@cX.blue}sisu#{@cX.off} is placed in #{@cX.blue}#{Config::CONFIG['bindir']}#{@cX.off} or #{@cX.blue}#{Config::CONFIG['sitelibdir']}#{@cX.off} and the library files, in #{@cX.blue}#{Config::CONFIG['rubylibdir']}/#{SiSU_lib}#{@cX.off}
- or in #{@cX.blue}#{Config::CONFIG['sitelibdir']}/#{SiSU_lib}#{@cX.off}
-
-  SiSU comes with a number of installers, including #{@cX.blue}setup.rb#{@cX.off}, #{@cX.blue}install#{@cX.off} and a #{@cX.blue}Rantfile#{@cX.off} if rant is installed on your system, you may need to be root to install sisu on your system. After unpacking the tarball, in the top directory of the tarball which contains the named files type, one of:
-      sudo ./sisu-install base
-      sudo ./sisu-install setup
-    if that does not work try
-      sudo ruby ./sisu-install setup
-    if rant is installed on your system you may instead run:
-      sudo rant base
-
-    for further options:
-      ./sisu-install -T
-
-  SiSU is pre-packaged for some GNU/Linux distributions such as Debian.

-  Note on databases built
-   By default, [unless otherwise specified] databases are built on a directory basis, from collections of documents within that directory.
-   The name of the directory you choose to work from is used as the database name,
-   i.e. if you are working in a directory called #{@cX.blue}#{@env.path.home}/ebook#{@cX.off} the database #{@cX.blue}#{Db[:name_prefix]}ebook#{@cX.off} is used. [otherwise a manual mapping for the collection is necessary]

-
-  NOTE: The examples that follow assume that sisu output is placed in the directory
-  /home/ralph/sisu_www
-
- (A)  to generate the index
-   within the webserver directory to be indexed:
-      #{@cX.orange}estcmd gather -sd [index name] [directory path to index]#{@cX.off}
-   the following are examples that will need to be tailored according to your needs:
-     #{@cX.green}
-     cd #{@env.path.webserv}
-     estcmd gather -sd casket #{@env.path.webserv}
-     #{@cX.off}
-     you may use the 'find' command together with 'egrep' to limit
-     indexing to particular document collection directories within
-     the web server directory:#{@cX.green}
-
-     find /home/ralph/sisu_www -type f | egrep '#{@env.path.output}/.+?\.html$' |estcmd gather -sd casket - #{@cX.off}
-
-     check which directories in the webserver/output directory #{@cX.green}#{@env.path.webserv}#{@cX.off}
-     you wish to include in the search index, these appear to be:
-
-     #{@env.path.webserv}/#{@cX.green}#{out_dir}#{@cX.off}
-
-     as sisu duplicates output in multiple file formats,
-     it it is probably preferable to limit the estraier index
-     to html output, and as it may also be desirable to
-     exclude files 'doc.html' and 'concordance.html', as these
-     duplicate information held in other html output e.g. #{@cX.green}
-
-     find /home/ralph/sisu_www -type f | egrep '/sisu_www/(sisu|bookmarks)/.+?\.html$' | egrep -v '(doc|concordance)\.html$' |estcmd gather -sd casket - #{@cX.off}
-
-     from your current document preparation/markup directory, you would construct a rune along the following lines: #{@cX.green}
-
-     find /home/ralph/sisu_www -type f | egrep '#{@env.path.webserv}/([specify first directory for inclusion]|[specify second directory for inclusion]|[another directory for inclusion? ...])/.+?\.html$' | egrep -v '(doc|concordance)\.html$' |estcmd gather -sd #{@env.path.webserv}/casket - #{@cX.off}
-
- (B) to set up the search form
-   (i) copy #{@cX.green}estseek.cgi#{@cX.off} to your cgi directory and set file permissions to 755: #{@cX.green}
-
-     sudo cp -vi /usr/lib/estraier/estseek.cgi /usr/lib/cgi-bin
-     sudo chmod -v 755 /usr/lib/cgi-bin/estseek.cgi
-     sudo cp -v /usr/share/hyperestraier/estseek.* /usr/lib/cgi-bin #{@cX.off}
-     [see estraier documentation for paths]
-
-   (ii) edit #{@cX.green}estseek.conf#{@cX.off}, with attention to the lines starting 'indexname:' and 'replace:': #{@cX.green}
-
-     indexname: #{@env.path.webserv}/casket
-     replace: ^file://#{@env.path.webserv}{{!}}#{@env.url.webserv_host_base}
-     replace: /index\.html?${{!}}/ #{@cX.off}
-
- (C) to test using webrick, start webrick: #{@cX.green}
-     sisu -W #{@cX.off}
-
-   and try open the url: #{@cX.blue}
-     #{@env.url.webserv_host_base}/cgi-bin/estseek.cgi #{@cX.off}

-Types of tag,
-
-then there are various tags which occur within the document.
-Structural tags, which consist of:
-  heading tags that identify headings within text, and;
-  footnote/endnote tags ...
-
-Markup instructions: giving information as to what is to be done to the presentation of the text
-
-Markup tags
-
-These have been kept to a minimum. A number of text html markup tags can be used <b>to bold</b> <i>to indent</i> <sup>for superscript</sup> <sub>for subscript text</sub>
-
-_1 at the beginning of a line indents the paragraph
-
-_2 at the beginning of a line double indents the paragraph
-
-Others include
-
-Other things to note:
-
-By default paragraphs are automatically numbered... and is the same across all output formats
-This makes citation a lot easier... regardless of the form of output that is being looked at
-It also permits the building of various addons, like the concordance feature which identifies each word and the paragraphs in which the word appears with links to the paragraph...
-
-Urls are automatically turned to live links in the html and pdf files created...
