    data/doc/sisu/sisu_markup_samples/sisu_manual/
    /usr/share/doc/sisu/sisu_markup_samples/sisu_manual/
  * default output [sisu -3] in
    data/doc/manuals_generated/sisu_manual/
    /usr/share/doc/manuals_generated/sisu_manual/
    (adds substantially to the size of sisu package!)

* help related edits

* manpage, work on ability to generate manpages, improved

* param, exclude footnote mark count when occurs within code block

* plaintext changes made

* shared_txt, line wrap visited

* file:// link option introduced (in addition to existing https?:// and
  ftp://) a bit arbitrarily, diff here, [double check changes in sysenv and
  hub]

* minor adjustments
  * html url match refinement
  * css added tiny_center

* plaintext
  * endnotes fix
  * footnote adjustment to make more easily distinguishable from substantive
    text
  * flag -a only [flags -A -e -E dropped]
    controlled by modifiers --unix/msdos --footnote/endnote

* defaults, homepage
  * renamed homepage (instead of index) implications for modifying skins,
    which need likewise to have any homepage entry renamed
  * added link to sisu_manual in homepage

* css the css for the default homepage is renamed homepage.css (instead of
  index.css) [consider removing this and relying on html.css]
