documents - structuring, publishing in multiple formats and search

 SiSU is a lightweight markup based, command line oriented, document
 structuring, publishing and search framework for document collections.
 .
 With minimal preparation of a plain-text (UTF-8) file, using sisu markup
 syntax in your text editor of choice, SiSU can generate various document
 formats (most of which share a common object numbering system for locating
 content), including plain text, HTML, XHTML, XML, EPUB, OpenDocument text
 (ODF:ODT), LaTeX, PDF files, and populate an SQL database with objects
 (roughly paragraph-sized chunks) so searches may be performed and matches
 returned with that degree of granularity. Think being able to finely match
 text in documents across different output formats and across languages if you
 have translations of the same document, using common object numbers.
 Additionally for search, your criteria is met by these documents at these
 locations within each document (equally relevant across different output
 formats and languages). To be clear (if obvious) page numbers provide none of
 this functionality. Object numbering 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. Document
 outputs also share semantic meta-data provided.
 .
 SiSU also provides concordance files, document content certificates and
 manifests of generated output. SiSU provides the means to make book indexes
 that make use of its object numbering.
 .
 A vim syntax highlighting file and an ftplugin with folds for sisu markup is
 provided. Vim 7 includes syntax highlighting for SiSU. Some syntax hilighting
 is also available for Emacs and a few other editors.
 .
 Dependencies for various features are taken care of in sisu related packages.
 The package sisu-complete installs the whole of SiSU.
 .
 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.
 .
 SiSU uses utf-8 & parses left to right. Currently supported languages:
 am bg bn br ca cs cy da de el en eo es et eu fi fr ga gl he hi hr hy ia is it
 ja ko la lo lt lv ml mr nl nn no oc pl pt pt_BR ro ru sa se sk sl sq sr sv ta
 te th tk tr uk ur us vi zh (see XeTeX polyglossia & cjk)
 .
 SiSU works well under po4a translation management, for which an administrative
 sample Rakefile is provided with sisu_manual under markup-samples.
