-%% Description
----------------
-
-  SiSU is lightweight markup based document creation and publishing framework
-  that is controlled from the command line.  Prepare documents for SiSU using
-  your text editor of choice, then use SiSU to generate various output document
-  formats.
+SISU - README
+=============
 
-  With minimal preparation of a plain-text (UTF-8) file using its native
-  markup-syntax, SiSU produces: plain-text, HTML, XHTML, XML, EPUB (v2 only)
-  ODF:ODT (Opendocument), LaTeX, PDF, and populates an SQL database (PostgreSQL
-  or SQLite) with text objects, roughly, paragraph sized chunks so that
-  document searches are done at this level of granularity.
+INTRODUCTION
+************
 
-  Outputs share a common citation numbering system, associated with text
-  objects and any semantic meta-data provided about the document.
+INTRODUCTION - WHAT IS SISU?
+----------------------------
 
-  SiSU also provides concordance files, document content certificates and
-  manifests of generated output. Book indexes may be made.
+*SiSU* is a lightweight markup based document creation and publishing framework
+that is controlled from the command line. Prepare documents for *SiSU* using
+your text editor of choice, then use *SiSU* to generate various output document
+formats.
 
-    SiSU takes advantage of well established open standard ways of representing
-    text, and provides a bridge to take advantage of the strengths of each,
-    while retaining minimal markup requirement. SiSU implements a "useful
-    common feature set" across document formats [coming from a humanities, law,
-    and possibly social sciences perspective, rather than technical or
-    scientific writing] ...  focus is primarily on content and data integrity
-    rather than appearance, (though outputs in the various formats are
-    respectable).
+From a single lightly prepared document (plain-text /UTF-8/) 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's
+structure and content from which it is possible to generate different forms of
+representation of the document. *SiSU* produces: plain-text, /HTML/, /XHTML/,
+/XML/, /EPUB/, /ODF/: /ODT/ (Opendocument), /LaTeX/, /PDF/, and populates an
+/SQL/ database (/PostgreSQL/ or /SQLite/) with text objects, roughly, paragraph
+sized chunks so that document searches are done at this level of granularity.
 
-  Syntax highlighting files for a number of editors are provided.
-  A vim syntax highlighting file and an ftplugin with folds for sisu markup is
-  provided. Vim 7 includes syntax highlighting for SiSU.
+Outputs share a common citation numbering system, associated with text objects
+and any semantic meta-data provided about the document.
 
-  man pages, and interactive help are provided.
+*SiSU* also provides concordance files, document content certificates and
+manifests of generated output. Book indexes may be made.
 
-  Dependencies for various features are taken care of in sisu related packages.
-  The package sisu-complete installs the whole of SiSU.
+Some document markup samples are provided in the package sisu -markup-samples.
 
-  Additional document markup samples are provided in the package
-  sisu-markup-samples which is found in the non-free archive the licenses for
-  the substantive content of the marked up documents provided is that provided
-  by the author or original publisher.

----------
+SOURCE TARBALL
+--------------
 
-The ideas behind SiSU evolved working with managing static, published documents
-that needed to be citable, ideally searchable and preferably available in
-multiple formats over a period of time with a rapidly changing World Wide Web.
-Initial experience was in 1993, one issue being that the document content
-remained the same, but presentation needed to be updated with changing formats,
-html in particular has really changed since then.
+RUN OFF SOURCE PACKAGE DIRECTORY TREE (WITHOUT INSTALLING)
+..........................................................
 
-So the idea was to provide a minimal markup requirement for documents that
-remained the same, and a generator to convert that markup custom producing
-various output types. This made it possible to:
+1. Download the latest source (information available) from:
+<http://www.jus.uio.no/sisu/SiSU/download.html#current>
 
-* have a marked-up document set and continue improving the presentation, as the
-generators code was updated, e.g. update HTML as it evolves, and improve upon
-LaTeX driven pdf output
+2. Unpack the source
 
-* have available new document formats/ output types as they came to be of
-interest, e.g. version 2 includes EPUB
+Provided you have *Ruby*, *SiSU* can be run without installation straight from
+the source package directory tree. Run ruby against the full path to bin/sisu
+(in the unzipped source package directory tree)
 
-* produce a citation system that is available across different output types,
-text based on objects (rather than page numbers), i.e. you can accurately and
-reliably cite text within a document regardless of the document format version
-that is being looked at
+Note however, that additional external package dependencies, such as texlive
+(for pdfs), sqlite3 or postgresql (for search) should you desire to use them
+are not taken care of for you.
 
-* take advantage of the strengths of disparate technologies representing text,
-each output type being custom generated for that format, the object citation
-system lends itself as a result is that there is little necessity that one
-output type should be based on or related to another, just that the content is
-preserved and presented in a way that is well suited to the output type in
-question
+GEM INSTALL (WITH RAKE)
+.......................
 
-* produce consistent quality presentation for material, suitable where
-substance/content is more important than appearance, there is some sacrifice of
-flexibility and no concept of wysiwyg, e.g. there is no attempt to make pdf
-output identical to html, rather the system attempts to take advantage of
-making the best presentation it can in each output format taking advantage of
-the strengths of that format available to it given the minimal markup (sisu
-document preparation); the citation system ensures you can pinpoint the same
-text
+Gem install, you need to:
 
-SiSU works best:
+(i) create the gemspec; (ii) build the gem (from the gemspec); (iii) install
+the gem
 
-* with published works (e.g. books, articles), static documents the content of
-which is changed rarely, and ideally when they do in the form of a new edition.
+Provided you have ruby & rake, this can be done with the single command:
 
-* for literature and law related content
+  rake gem_create_build_install # (to build and install sisu v5 & sisu v6,
+  alias gemcbi)
 
-SiSU uses Unicode, utf-8 where it is available,
------
+separate gems are made/installed for sisu v5 & sisu v6 contained in source:
 
-SiSU - simple information structuring universe, is a publishing tool, document
-generation and management, (and search enabling) tool primarily for literary,
-academic and legal published works.
+  rake gem_create_build_install_stable # (to build and install sisu v5, alias
+  gem5cbi)
 
-SiSU can be used for Internet, Intranet, local filesystem or cd publishing.
+  rake gem_create_build_install_unstable # (to build and install sisu v6, alias
+  gem6cbi)
 
-SiSU can be used directly off the filesystem, or from a database.
+for individual steps (create, build, install) see rake options, rake -T to
+specify sisu version for sisu installed via gem
 
-SiSU's scalability, is be dependent on your hardware, and filesystem and/or
-database Postgresql.
+  sisu _5.3.0_ --version
 
-Amongst it's characteristics are:
+  sisu _6.0.0_ --version
 
-* simple mnemonoic markup style,
+to uninstall sisu installed via gem
 
-* the ability to produce multiple output formats, including html, XML, EPUB,
-LaTeX, pdf (via LaTeX), stream to a relational database whilst retaining
-document structure - Postgresql and Sqlite,
+  sudo gem uninstall --verbose sisu
 
-* that all share a common citation system (a simple idea from which much good),
-possibly most exciting, the following: if fed into a relational database (as it
-can be automatically), the document set is searchable, with results displayed
-at a paragraph level, or the possibility of an indexed display of documents
-identifying the paragraph in which the match is found (using the object
-citation numbering system) together with a hyperlinked listing for each of each
-paragraph in which the match is found. In any event citations using this system
-(with or without the relational database) are relevant for all output formats.
+For a list of alternative actions you may type:
 
-* it is command line driven, and can be set up on a remote server
+  rake help
 
-* Documents are marked up in SiSU syntax in your favourite editor. SiSU syntax
-may be regarded as a type of smart ascii - which in its basic form is simpler
-than the most elementary html. There is currently a syntax highlighter, and
-folding for Vim. Syntax highlighters for other editors are welcome.
+  rake -T
 
-Input files should be UTF-8
+Rake: <http://rake.rubyforge.org/> <http://rubyforge.org/frs/?group_id=50>
 
-Once set up it is simple to use.

+INSTALLATION WITH SETUP.RB
+..........................
 
-Within the SiSU tarball:
+It should also be possible to install sisu using setup.rb
 
-  ./data/doc/sisu/v2/sisu_markup_samples/sisu_manual
+this is a three step process, in the root directory of the unpacked *SiSU* as
+root type:
 
-Once installed, directory equivalent to:
+ruby setup.rb config
+ruby setup.rb setup
+#[as root:]
+ruby setup.rb install
 
-  <file:///usr/share/doc/sisu/v2/sisu_markup_samples/sisu_manual/>

+
+COMMANDS SUMMARY
+----------------
+
+DESCRIPTION
+...........
+
+*SiSU* is a document publishing system, that from a simple single marked-up
+document, produces multiple output formats including: /plaintext/, /HTML/,
+/XHTML/, /XML/, /EPUB/, /ODT/ (/OpenDocument/ (/ODF/) text), /LaTeX/, /PDF/,
+info, and /SQL/ (/PostgreSQL/ and /SQLite/) , which share text object numbers
+("object citation numbering") and the same document structure information. For
+more see: <http://sisudoc.org> or <http://www.jus.uio.no/sisu>
+
+DOCUMENT PROCESSING COMMAND FLAGS

+include: --endnotes for endnotes --footnotes for footnotes at the end of each
+paragraph --unix for unix linefeed (default) --msdos for msdos linefeed)
+
+*--ao [filename/wildcard/url]*
+assumed for most other flags, creates new intermediate files for processing

+see --po4a
+
+*--po4a [language_directory/filename language_directory]*
+produces .pot and po files for the file in the languages specified by the
+language directory. *SiSU* markup is placed in subdirectories named with the
+language code, e.g. en/ fr/ es/. The sisu config file must set the output

+*-r [filename/wildcard]*
+see --scp
+
+*--redirect[=directory_path] [filename/wildcard]*
+places output in subdirectory under specified directory, subdirectory uses the

+
+*--rst [filename/wildcard/url]*
+ReST (rST restructured text) smart text (sisu v5)
+
+*--rsync [filename/wildcard]*
+copies sisu output files to remote host using rsync. This requires that
+sisurc.yml has been provided with information on hostname and username, and
+that you have your "keys" and ssh agent in place. Note the behavior of rsync
+different if -R is used with other flags from if used alone. Alone the rsync
+--delete parameter is sent, useful for cleaning the remote directory (when -R
+is used together with other flags, it is not). Also see --scp. Alias -R

+*-S [filename/wildcard]*
+see --sisupod
+
+*-s [filename/wildcard]*
+see --source
+
+*--sample-search-form [--db=(pgsql|sqlite)] [--webserv=webrick]*
+generate examples of (naive) cgi search form for /SQLite/ or PgSQL depends on
+your already having used sisu to populate an /SQLite/ 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 --sqlite & --pg and the database section below. Optional
+additional parameters include: url location of webserver search form and db:
+--webserv-search='[url]'; location of webserver output:
+--webserv-output='[url]'; cgi search form link name:
+--cgi-search-form-name='[name.cgi]'; for pgsql, database user:
+--db-user='[username]'. If the optional parameter --webserv=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). Alias -F
+
+*--scp [filename/wildcard]*
+copies sisu output files to remote host using scp. This requires that
+sisurc.yml has been provided with information on hostname and username, and
+that you have your "keys" and ssh agent in place. Also see --rsync. Alias -r
+
+*--sqlite --[instruction] [filename]*
+database type set to /SQLite/, this produces one of two possible databases,
+without additional database related instructions it produces a discreet
+/SQLite/ file for the document processed; with additional instructions it
+produces a common /SQLite/ database of all processed documents that (come from
+the same document preparation directory and as a result) share the same output
+directory base path (possible instructions include: --createdb; --create;
+--dropall; --import [filename]; --update [filename]; --remove [filename]); see
+database section below. Alias -d
+
+*--sisupod*
+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 -S [filename/wildcard] option. Note: (this option
+is tested only with zsh). Alias -S
+
+*--sisupod [filename/wildcard]*
+produces a zipped file of the prepared document specified along with associated
+images, by default named sisupod.zip they may alternatively be named with the
+filename extension .ssp This provides a quick way of gathering the relevant
+parts of a sisu document which can then for example be emailed. A sisupod
+includes sisu markup source file, (along with associated documents if a master
+file, or available in multilingual versions), together with related images and
+skin. *SiSU* commands can be run directly 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. The directory
+structure of the unzipped file is understood by sisu, and sisu commands can be
+run within it. Note: if you wish to send multiple files, it quickly becomes
+more space efficient to zip the sisu markup directory, rather than the
+individual files for sending). See the -S option without [filename/wildcard].
+Alias -S
+
+*--source [filename/wildcard]*
+copies sisu markup file to output directory. Alias -s
+
+*--strict*

+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 output 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

+see --zap
+
+*--zap [filename/wildcard]*
+Zap, if used with other processing flags deletes output files of the type about

+the related document output directory. Alias -Z
+
+COMMAND LINE MODIFIERS
+----------------------
+

+DATABASE COMMANDS
+-----------------
+
+*dbi - database interface*
+
+*-D or --pgsql* set for /PostgreSQL/ *-d or --sqlite* default set for /SQLite/
+-d is modifiable with --db=[database type (PgSQL or /SQLite/) ]
+
+*--pg -v --createall*
+initial step, creates required relations (tables, indexes) in existing
+/PostgreSQL/ database (a database should be created manually and given the same
+name as working directory, as requested) (rb.dbi) [ -dv --createall /SQLite/
+equivalent] it may be necessary to run sisu -Dv --createdb initially NOTE: at
+the present time for /PostgreSQL/ it may be necessary to manually create the
+database. The command would be 'createdb [database name]' where database name
+would be SiSU_[present working directory name (without path)]. Please use only
+alphanumerics and underscores.
+
+*--pg -v --import*
+[filename/wildcard] imports data specified to /PostgreSQL/ db (rb.dbi) [ -dv
+--import /SQLite/ equivalent]
+
+*--pg -v --update*
+[filename/wildcard] updates/imports specified data to /PostgreSQL/ db (rb.dbi)
+[ -dv --update /SQLite/ equivalent]
+
+*--pg --remove*
+[filename/wildcard] removes specified data to /PostgreSQL/ db (rb.dbi) [ -d
+--remove /SQLite/ equivalent]
+
+*--pg --dropall*
+kills data" and drops (/PostgreSQL/ or /SQLite/) db, tables & indexes [ -d
+--dropall /SQLite/ equivalent]
+
+The -v is for verbose output.
+
+SHORTCUTS, SHORTHAND FOR MULTIPLE FLAGS
+---------------------------------------
+
+*--update [filename/wildcard]*
+Checks existing file output and runs the flags required to update this output.
+This means that if only html and pdf output was requested on previous runs,
+only the -hp files will be applied, and only these will be generated this time,
+together with the summary. This can be very convenient, if you offer different
+outputs of different files, and just want to do the same again.
+
+*-0 to -5 [filename or wildcard]*
+Default shorthand mappings (for v3, note that the defaults can be
+changed/configured in the sisurc.yml file):
+
+*-0*
+-NQhewpotbxXyYv [this is the default action run when no options are give, i.e.
+on 'sisu [filename]']
+
+*-1*
+-Qhewpoty
+
+*-2*
+-NQhewpotbxXy
+
+*-3*
+-NQhewpotbxXyY
+
+*-4*
+-NQhewpotbxXDyY --update
+
+*-5*
+-NQhewpotbxXDyYv --update
+
+add -v for verbose mode and -c to toggle color state, e.g. sisu -2vc [filename
+or wildcard]
+
+consider -u for appended url info or -v for verbose output
+
+COMMAND LINE WITH FLAGS - BATCH PROCESSING
+..........................................
+
+In the data directory run sisu -mh filename or wildcard eg. "sisu -h cisg.sst"
+or "sisu -h *.{sst,ssm}" to produce html version of all documents.
+
+Running sisu (alone without any flags, filenames or wildcards) brings up the
+interactive help, as does any sisu command that is not recognised. Enter to
+escape.
+
+INTRODUCTION TO SISU MARKUP[^3]
+-------------------------------
+
+SUMMARY
+.......
+
+*SiSU* source documents are /plaintext/ (/UTF-8/)[^4] files
+
+All paragraphs are separated by an empty line.
+
+Markup is comprised of:
+
+* 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)
+
+* 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:
+
+  * heading levels defines document structure
+
+  * text basic attributes, italics, bold etc.
+
+  * grouped text (objects), which are to be treated differently, such as code
+  blocks or poems.
+
+  * footnotes/endnotes
+
+  * linked text and images
+
+  * paragraph actions, such as indent, bulleted, numbered-lists, etc.
+
+Some interactive help on markup is available, by typing sisu and selecting
+markup or sisu --help markup
+
+To check the markup in a file:
+
+  sisu --identify [filename].sst
+
+For brief descriptive summary of markup history
+
+  sisu --query-history
+
+or if for a particular version:
+
+  sisu --query-0.38
+
+MARKUP EXAMPLES
+...............
+
+
+----------------------------------------
+
+ONLINE
+......
+
+Online markup examples are available together with the respective outputs
+produced from <http://www.jus.uio.no/sisu/SiSU/examples.html> or from
+<http://www.jus.uio.no/sisu/sisu_examples/>
+
+There is of course this document, which provides a cursory overview of sisu
+markup and the respective output produced:
+<http://www.jus.uio.no/sisu/sisu_markup/>
+
+an alternative presentation of markup syntax:
+/usr/share/doc/sisu/on_markup.txt.gz
+
+
+----------------------------------------
+
+INSTALLED
+.........
+
+With *SiSU* installed sample skins may be found in:
+/usr/share/doc/sisu/markup-samples (or equivalent directory) and if sisu
+-markup-samples is installed also under:
+/usr/share/doc/sisu/markup-samples-non-free
+
+MARKUP OF HEADERS
+-----------------
+
+Headers contain either: semantic meta-data about a document, which can be used
+by any output module of the program, or; processing instructions.
+
+Note: the first line of a document may include information on the markup
+version used in the form of a comment. Comments are a percentage mark at the
+start of a paragraph (and as the first character in a line of text) followed by
+a space and the comment:
+
+% this would be a comment

+AVAILABLE HEADERS
+.................
+
+Header tags appear at the beginning of a document and provide meta information
+on the document (such as the /Dublin Core/) , or information as to how the
+document as a whole is to be processed. All header instructions take the form
+@headername: or on the next line and indented by once space :subheadername: All
+/Dublin Core/ meta tags are available
+
+*@identifier:* information or instructions
+
+where the "identifier" is a tag recognised by the program, and the
+"information" or "instructions" belong to the tag/identifier specified
+
+Note: a header where used should only be used once; all headers apart from
+@title: are optional; the @structure: header is used to describe document
+structure, and can be useful to know.

+MARKUP OF SUBSTANTIVE TEXT
+--------------------------
+
+HEADING LEVELS
+..............
+
+Heading levels are :A~ ,:B~ ,:C~ ,1~ ,2~ ,3~ ... :A - :C being part / section
+headings, followed by other heading levels, and 1 -6 being headings followed by
+substantive text or sub-headings. :A~ usually the title :A~? conditional level
+1 heading (used where a stand-alone document may be imported into another)
+
+*:A~ [heading text]* Top level heading [this usually has similar content to the
+title @title: ] NOTE: the heading levels described here are in 0.38 notation,
+see heading
+
+*:B~ [heading text]* Second level heading [this is a heading level divider]
+
+*:C~ [heading text]* Third level heading [this is a heading level divider]
+
+*1~ [heading text]* Top level heading preceding substantive text of document or
+sub-heading 2, the heading level that would normally be marked 1. or 2. or 3.
+etc. in a document, and the level on which sisu by default would break html
+output into named segments, names are provided automatically if none are given
+(a number), otherwise takes the form 1~my_filename_for_this_segment
+
+*2~ [heading text]* Second level heading preceding substantive text of document
+or sub-heading 3 , the heading level that would normally be marked 1.1 or 1.2
+or 1.3 or 2.1 etc. in a document.

+FOOTNOTES / ENDNOTES
+....................
+
+Footnotes and endnotes are marked up at the location where they would be
+indicated within a text. They are automatically numbered. The output type
+determines whether footnotes or endnotes will be produced
+
+*markup example:*
+
+~{ a footnote or endnote }~
+
+
+*resulting output:*
+
+[^5]
+
+*markup example:*
+
+normal text~{ self contained endnote marker & endnote in one }~ continues
+
+
+*resulting output:*
+
+normal text[^6] continues
+
+*markup example:*
+
+normal text ~{* unnumbered asterisk footnote/endnote, insert multiple asterisks if required }~ continues
+
+normal text ~{** another unnumbered asterisk footnote/endnote }~ continues
+
+
+*resulting output:*
+
+normal text [^*] continues
+
+normal text [^**] continues

+----------------------------------------
+
+NAKED URLS WITHIN TEXT, DEALING WITH URLS
+.........................................
+
+urls found within text are marked up automatically. A url within text is
+automatically hyperlinked to itself and by default decorated with angled
+braces, unless they are contained within a code block (in which case they are
+passed as normal text), or escaped by a preceding underscore (in which case the
+decoration is omitted).
+
+*markup example:*
+
+normal text http://www.sisudoc.org/ continues
+
+
+*resulting output:*
+
+normal text <http://www.sisudoc.org/> continues
+
+An escaped url without decoration
+
+*markup example:*
+
+normal text _http://www.sisudoc.org/ continues
+
+deb _http://www.jus.uio.no/sisu/archive unstable main non-free
+
+
+*resulting output:*
+
+normal text http://www.sisudoc.org/ continues
+
+deb http://www.jus.uio.no/sisu/archive unstable main non-free
+
+where a code block is used there is neither decoration nor hyperlinking, code
+blocks are discussed later in this document
+
+*resulting output:*
+
+deb http://www.jus.uio.no/sisu/archive unstable main non-free
+deb-src http://www.jus.uio.no/sisu/archive unstable main non-free
+

+
+LINKING TEXT
+............
+
+To link text or an image to a url the markup is as follows
+
+*markup example:*
+
+about { SiSU }http://url.org markup
+
+
+*resulting output:*
+
+about SiSU [link: <http://www.sisudoc.org/>] markup
+
+A shortcut notation is available so the url link may also be provided
+automatically as a footnote
+
+*markup example:*
+
+about {~^ SiSU }http://url.org markup
+
+
+*resulting output:*
+
+about SiSU [link: <http://www.sisudoc.org/>] [^7] markup
+
+Internal document links to a tagged location, including an ocn
+
+*markup example:*
+
+about { text links }#link_text

+
+LINKING IMAGES
+..............
+
+*markup example:*
+

+
+% various url linked images
+[image: "a better way"]
+ [image: "Way Better - with Gnu/Linux, Debian and Ruby"]
+

+
+GnuDebianLinuxRubyBetterWay.png 100x101 "Way Better - with Gnu/Linux, Debian
+and Ruby" [link: <http://www.sisudoc.org/>]
+
+ruby_logo.png 70x90 "Ruby" [link: <http://www.ruby-lang.org/en/>] [^8]
+
+*linked url footnote shortcut*
+
+{~^ [text to link] }http://url.org
+
+% maps to: { [text to link] }http://url.org ~{ http://url.org }~
+
+% which produces hyper-linked text within a document/paragraph, with an endnote providing the url for the text location used in the hyperlink
+
+
+text marker *~name
+
+
+note at a heading level the same is automatically achieved by providing names
+to headings 1, 2 and 3 i.e. 2~[name] and 3~[name] or in the case of
+auto-heading numbering, without further intervention.

---------------
-Once installed see 'man 8 sisu' for some information on additional programs
-that sisu makes use of, and that you may need or wish to install. (this will
-depend on such factors as whether you want to generate pdf, whether you will be
-using SiSU with or without a database, ...) 'man sisu_markup-samples' may also be of
-interest if the sisu-markup-samples package has also been installed.
-
-The information in man 8 may not be most up to date, and it is possible that
-more useful information can be gleaned from the following notes taken from the
-Debian control file (end edited), gives an idea of additional packages that
-SiSU can make use of if available, (the use/requirement of some of which are
-interdependent for specific actions by SiSU):

-Suggests: evince, xpdf
+BOOK INDEX
+..........
 
-Package: sisu-postgresql
-Depends: sisu, postgresql-8.1, libdbi-ruby, libdbm-ruby, libdbd-pg-ruby
-Suggests: pgaccess, libdbd-pgsql, postgresql-contrib-8.1
+To make an index append to paragraph the book index term relates to it, using
+an equal sign and curly braces.
 
-Package: sisu-sqlite
-Depends: sisu, sqlite, libdbi-ruby, libdbm-ruby, libdbd-sqlite-ruby
-Suggests: libdbd-sqlite
+Currently two levels are provided, a main term and if needed a sub-term.
+Sub-terms are separated from the main term by a colon.
 
-Package: sisu-markup-samples
-Depends: sisu
+  Paragraph containing main term and sub-term.
+  ={Main term:sub-term}
 
-%% Quick start
----------------
-Most of the installation should be taken care of by the aptitude or rant
-install. (The rant install if run in full will also test run the generation of
-the first document).
 
-After installation of sisu-complete, move to the document samples directory
+The index syntax starts on a new line, but there should not be an empty line
+between paragraph and index markup.
 
-  cd /usr/share/doc/sisu/v2/sisu_markup_samples/dfsg
+The structure of the resulting index would be:
 
-and run
+  Main term, 1
+    sub-term, 1
 
-  sisu -3 free_as_in_freedom.rms_and_free_software.sam_williams.sst
 
-[or the same:
-  sisu  -NhwpoabxXyv free_as_in_freedom.rms_and_free_software.sam_williams.sst
-]
+Several terms may relate to a paragraph, they are separated by a semicolon. If
+the term refers to more than one paragraph, indicate the number of paragraphs.
 
-look at output results, see the "sisu_manifest" page created for the document
+  Paragraph containing main term, second term and sub-term.
+  ={first term; second term: sub-term}
 
-or to generate an online document move to a writable directory, as the file
-will be downloaded there and e.g.
 
-sisu -3 http://www.jus.uio.no/sisu/free_culture.lawrence_lessig/free_culture.lawrence_lessig.sst
+The structure of the resulting index would be:
 
-the database stuff is extra perhaps, the latex stuff could be considered extra
-perhaps but neither needs to be installed for most of sisu output to work
+  First term, 1,
+  Second term, 1,
+    sub-term, 1
 
-examine source document, vim has syntax support
 
-gvim free_as_in_freedom.rms_and_free_software.sam_williams.sst
+If multiple sub-terms appear under one paragraph, they are separated under the
+main term heading from each other by a pipe symbol.
 
-additional markup samples in
-<http://www.jus.uio.no/sisu/SiSU/2.html>
+  Paragraph containing main term, second term and sub-term.
+  ={Main term:
+      sub-term+2|second sub-term;
+    Another term
+   }
 
-For help
- man sisu
+  A paragraph that continues discussion of the first sub-term
 
-%% Configuration files
----------------
 
-The default configuration/setup is contained within the program and is altered
-by configuration settings in /etc/[sisu version]/sisurc.yml
-or in ~/.sisu/sisurc.yml
+The plus one in the example provided indicates the first sub-term spans one
+additional paragraph. The logical structure of the resulting index would be:
 
-* configuration file - a yaml file
-  /etc/sisu/[sisu version]/sisurc.yml
-  ~/.sisu/sisurc.yml
+  Main term, 1,
+    sub-term, 1-3,
+    second sub-term, 1,
+  Another term, 1
 
-* directory structure - setting up of output and working directory.
 
-* skins - changing the appearance of a project, directory or individual
-documents within ~/.sisu/skin
-  ~/.sisu/skin/doc contains individual skins, with symbolic links from
-  ~/.sisu/skin/dir if the contents of a directory are to take a particular
-  document skin.
+COMPOSITE DOCUMENTS MARKUP
+--------------------------
 
-* additional software - eg. Tex and LaTeX (tetex, tetex-base, tetex-extra on
-Debian), Postgresql, [sqlite], trang, tidy, makeinfo,  ... none of which are
-required for basic html or XML processing.
+It is possible to build a document by creating a master document that requires
+other documents. The documents required 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 *.ssm* 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 *.sst* regular markup file, or *.ssi*
+(insert/information) A secondary file of the composite document is built prior
+to processing with the same prefix and the suffix *._sst*
 
-* if you use Vim as editor there is a syntax highlighter and fold resource
-config file for SiSU. I hope more syntax highlighters follow.
+basic markup for importing a document into a master document
 
-There are post installation steps (which are really part of the overall
-installation)
+<< filename1.sst
 
-sisu -C in your marked up document directory, should do some auto-configuring
-provided you have the right permissions for the output directories. (and
-provided the output directories have already been specified if you are not
-using the defaults).
+<< filename2.ssi
 
-%% Use General Overview
----------------
-Documents are marked up in SiSU syntax and kept in an ordinary text editable
-file, named with the suffix .sst, or .ssm
 
-Marked up SiSU documents are usually kept in a sub-directory of your choosing
+The form described above should be relied on. Within the /Vim/ editor it
+results in the text thus linked becoming hyperlinked to the document it is
+calling in which is convenient for editing.
 
-%% Help

+SUBSTITUTIONS
+-------------
 
-interactive help described below, or man page:
+*markup example:*
 
-  man sisu
+The current Debian is ${debian_stable} the next debian will be ${debian_testing}
 
-  man 8 sisu
- 'man sisu_markup-samples' [if the sisu-markup-samples package is also installed]
+Configure substitution in _sisu/sisu_document_make
 
-%% Directory Structure
----------------
-Once installed, type:
-  sisu -V
+@make:
+:substitute: /${debian_stable}/,'*{Wheezy}*' /${debian_testing}/,'*{Jessie}*'
 
-%% Configuration File
----------------
 
-The defaults can be changed via SiSU's configure file sisurc.yml which the
-program expects to find in ./_sisu ~/.sisu or /etc/sisu (searched in that
-order, stopping on the first one found)
+*resulting output:*
 
-%% Markup
----------------
+The current *Debian* is *Wheezy* the next debian will be *Jessie*
 
-See man pages.
-  man sisu
+Configure substitution in _sisu/sisu_document_make
 
-  man 8 sisu
 
-Sample marked up document are provided with the download tarball in the
-directory:
-  ./data/doc/sisu/v2/sisu_markup_samples/dfsg
+----------------------------------------
 
-These are installed on the system usually at:
-  /usr/share/doc/sisu/v2/sisu_markup_samples/dfsg
 
-More markup samples are available in the package sisu-markup-samples

-%% Additional Things
----------------
+ [1]: <http://packages.qa.debian.org/s/sisu.html>
 
-There is syntax support for some editors provided (together with a README file) in
+ [2]: from the *Debian* control file

-  /usr/share/sisu/v2/conf/editor-syntax-etc
+ [+1]: square brackets
 
-v1, v2 Changes
----------------
+ [3]: From sometime after SiSU 0.58 it should be possible to describe SiSU markup
+ using SiSU, which though not an original design goal is useful.
 
-See changelogs
+ [4]: files should be prepared using /UTF-8/ character encoding
 
-From a developer's perspective the substantive change between the two versions
-is to the middle layer, (the document abstraction, the intermediate document
-representation used in processing).  Version 1 uses strings and relies on
-regular expressions to identify document objects, while Version 2 uses ruby
-objects. The version 1 approach whilst programming language neutral offers less
-control, and leads to complicated code; version 2 approach takes advantage of
-features within the ruby language suited to what the application does.
-Development is curently on version 2, version 1 is likely to remain for some
-time as a reference implementation.
+ [5]: a footnote or endnote
 
-%% Versions
+ [6]: self contained endnote marker & endnote in one
 
-* v1 sisu pretty mature in operation and syntax
-* v2 introduces new processing middle layer (document abstraction);
-   markup same except for minor changes to document headers;

-* v3 introduces alternative (configurable) output structures
-* v4 retires what were referred to as sisu skins

-<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>

-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='sect50' href='#toc50'>Sisupod, Zipped Binary Container
-(sisupod.zip, .ssp)</a></h2>
-
-<p>  A sisupod is a zipped <b>SiSU</b> text file or set of <b>SiSU</b>
-text files and any associated images that they contain (this will be extended
-to include sound and multimedia-files)
-<p>
-<dl>
-
-<dt><b>SiSU</b> </dt>
-<dd><i>plaintext</i> files rely on a recognised
-directory structure to find contents such as images associated with documents,
-but all images for example for all documents contained in a directory are
-located in the sub-directory _sisu/image. Without the ability to create a
-sisupod it can be inconvenient to manually identify all other files associated
-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.
-
-<p>  The command to create a sisupod is:
-<p>  sisu -S [filename]
-<p>  Alternatively,
-make a pod of the contents of a whole directory:
-<p>  sisu -S
-<p>  <b>SiSU</b> processing
-can be done directly against a sisupod; which may be located locally or
-on a remote server for which a url is provided.

-<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
-</pre>
-<p>
-<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>

-by filetype or by filename, the selection is made in sisurc.yml

-<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> [^21] and/or <i>SQLite</i>
-[^22] 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>

 2~ Outline
 
+SiSU 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.
+
+SiSU is developed under an open source, software libre license (GPLv3). 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.
+
+SiSU both defines a markup syntax and provides an engine that produces open standards format outputs from documents prepared with SiSU 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's structure and content from which it is possible to generate different forms of representation of the document. Significantly SiSU markup is more sparse than html and outputs which include HTML, EPUB, ODT (Open Document Format text), LaTeX, landscape and portrait PDF, all of which can be added to and updated. SiSU is also able to populate SQL type databases at an object level, which means that searches can be made with that degree of granularity.
+
+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 SiSU markup applied to a document, SiSU custom builds (to take advantage of the strengths of different ways of representing documents) various standard open output formats including plain text, HTML, XHTML, XML, EPUB, ODT, LaTeX or PDF files, and populate an SQL database with objects~{ 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. }~ (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.
+
+In preparing a SiSU 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~{ i.e. the HTML, PDF, EPUB, ODT outputs are each built individually and optimised for that form of presentation, rather than for example the html being a saved version of the odf, or the pdf being a saved version of the html. }~ the different forms of output requested.
+
+SiSU works with an abstraction of the document based on its structure which is comprised of its headings~{ the different heading levels }~ and objects~{ units of text, primarily paragraphs and headings, also any tables, poems, code-blocks }~, which enables SiSU 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'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 SiSU is able to take advantage of.
+
+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. SiSU provides the flexibility of producing documents in multiple non-proprietary open formats including HTML, EPUB,~{ An open standard format for e-books }~ ODT,~{ Open Document Format (ODF) text }~ PDF~{ Specification submitted by Adobe to ISO to become a full open ISO specification \\ http://www.linux-watch.com/news/NS7542722606.html }~ ODF,~{ ISO standard ISO/IEC 26300:2006 }~. Whilst SiSU 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 SiSU can be migrated to other document formats. Further security is provided by the fact that the software itself, SiSU is available under GPLv3 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. SiSU 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), EPUB was introduced in 2009; and allows the technical representations existing output to be updated (HTML has evolved and the related module has been updated repeatedly over the years, presumably when the World Wide Web Consortium (w3c) finalises HTML 5 which is currently under development, the HTML module will again be updated allowing all existing documents to be regenerated as HTML 5).
+
+SiSU 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 SiSU offers great possibilities.
+
+SiSU is primarily for published works, which can take advantage of the citation system to reliably reference its documents. SiSU 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 SiSU.
+

+
+It should also be possible to install sisu using setup.rb
+
+this is a three step process, in the root directory of the unpacked SiSU as root type:
+
+``` code
+ruby setup.rb config
+ruby setup.rb setup
+#[as root:]
+ruby setup.rb install
+```
+

+A distribution install should take care of the dependencies of sisu for producing various outputs.
+
+2~ Debian
+
+SiSU is available off the Debian archives. It should necessary only to run as root, Using apt-get:
+
+code{
+
+  apt-get update
+
+  apt get install sisu-complete
+
+}code
+
+(all sisu dependencies should be taken care of)
+
+If there are newer versions of SiSU upstream, they will be available by
+adding the following to your sources list /etc/apt/sources.list *~sources.list
+
+code{
+
+#/etc/apt/sources.list
+
+deb http://www.jus.uio.no/sisu/archive unstable main non-free
+deb-src http://www.jus.uio.no/sisu/archive unstable main non-free
+
+}code
+
+The non-free section is for sisu markup samples provided, which contain authored works the substantive text of which cannot be changed, and which as a result do not meet the debian free software guidelines.
+
+SiSU is developed on Debian, and packages are available for Debian that take care of the dependencies encountered on installation.
+
+The package is divided into the following components:
+
+_1 *sisu*, the base code, (the main package on which the others depend), without any dependencies other than ruby (and for convenience the ruby webrick web server), this generates a number of types of output on its own, other packages provide additional functionality, and have their dependencies
+
+_1 *sisu-complete*, a dummy package that installs the whole of greater sisu as described below, apart from sisu-examples
+
+_1 *sisu-pdf*, dependencies used by sisu to produce pdf from LaTeX generated
+
+_1 *sisu-postgresql*, dependencies used by sisu to populate postgresql database (further configuration is necessary)
+
+_1 *sisu-sqlite*, dependencies used by sisu to populate sqlite database
+
+_1 *sisu-markup-samples*, sisu markup samples and other miscellany (under Debian Free Software Guidelines non-free)
+
+SiSU is available off { Debian Unstable and Testing }http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&subword=1&version=all&release=all&keywords=sisu ~{ http://packages.qa.debian.org/s/sisu.html }~ install it using apt-get, aptitude or alternative Debian install tools. *~apt-get

+1~sisu_intro Introduction - What is SiSU?
+
+SiSU is a lightweight markup based document creation and publishing framework that is controlled from the command line. Prepare documents for SiSU using your text editor of choice, then use SiSU to generate various output document formats.
+
+From a single lightly prepared document (plain-text UTF-8) 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's structure and content from which it is possible to generate different forms of representation of the document. SiSU produces: plain-text, HTML, XHTML, XML, EPUB, ODF:ODT (Opendocument), LaTeX, PDF, and populates an SQL database (PostgreSQL or SQLite) with text objects, roughly, paragraph sized chunks so that document searches are done at this level of granularity.
+
+Outputs share a common citation numbering system, associated with text objects and any semantic meta-data provided about the document.
+
+SiSU also provides concordance files, document content certificates and manifests of generated output. Book indexes may be made.
+
+Some document markup samples are provided in the package sisu-markup-samples.

-1~sisu_intro Introduction - What is SiSU?
-
-SiSU 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.
-
-SiSU is developed under an open source, software libre license (GPLv3). 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.
-
-SiSU both defines a markup syntax and provides an engine that produces open standards format outputs from documents prepared with SiSU 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's structure and content from which it is possible to generate different forms of representation of the document. Significantly SiSU markup is more sparse than html and outputs which include HTML, EPUB, ODT (Open Document Format text), LaTeX, landscape and portrait PDF, all of which can be added to and updated. SiSU is also able to populate SQL type databases at an object level, which means that searches can be made with that degree of granularity.
-
-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 SiSU markup applied to a document, SiSU custom builds (to take advantage of the strengths of different ways of representing documents) various standard open output formats including plain text, HTML, XHTML, XML, EPUB, ODT, LaTeX or PDF files, and populate an SQL database with objects~{ 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. }~ (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.
-
-In preparing a SiSU 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~{ i.e. the HTML, PDF, EPUB, ODT outputs are each built individually and optimised for that form of presentation, rather than for example the html being a saved version of the odf, or the pdf being a saved version of the html. }~ the different forms of output requested.
-
-SiSU works with an abstraction of the document based on its structure which is comprised of its headings~{ the different heading levels }~ and objects~{ units of text, primarily paragraphs and headings, also any tables, poems, code-blocks }~, which enables SiSU 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'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 SiSU is able to take advantage of.
-
-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. SiSU provides the flexibility of producing documents in multiple non-proprietary open formats including HTML, EPUB,~{ An open standard format for e-books }~ ODT,~{ Open Document Format (ODF) text }~ PDF~{ Specification submitted by Adobe to ISO to become a full open ISO specification <br> http://www.linux-watch.com/news/NS7542722606.html }~ ODF,~{ ISO standard ISO/IEC 26300:2006 }~. Whilst SiSU 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 SiSU can be migrated to other document formats. Further security is provided by the fact that the software itself, SiSU is available under GPLv3 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. SiSU 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), EPUB was introduced in 2009; and allows the technical representations existing output to be updated (HTML has evolved and the related module has been updated repeatedly over the years, presumably when the World Wide Web Consortium (w3c) finalises HTML 5 which is currently under development, the HTML module will again be updated allowing all existing documents to be regenerated as HTML 5).
-
-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.
-
-SiSU 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 SiSU offers great possibilities.
-
-SiSU is primarily for published works, which can take advantage of the citation system to reliably reference its documents. SiSU 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 SiSU.

-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's default font or using a different browser can mean that
-text will appear on a different page; and publishing in different formats,

-text. Dealing with documents at an object level together with object numbering
-also has implications for search that

-.BR
-One of the challenges of maintaining documents is to keep them in a format that

-proprietary software/equipment) in 15 years time, or the way the way in which
-html has evolved over its relatively short span of existence.

-open formats including

-.I ODT,

-.I PDF
-[^7]
-.I ODF,
-[^8]. Whilst
 .B SiSU
-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
-can be migrated to other document formats. Further security is provided by the
-fact that the software itself,
-.B SiSU
-is available under
-.I GPLv3
-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
-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
-was introduced in 2009; and allows the technical representations existing
