-;;{{{ Commentary:
-
-;;
-;; To enter sisu-mode automatically, add (autoload 'sisu-mode "sisu-mode")
-;; to your .emacs file and change the first line of your sisu file to:
-;; # -*- Sisu -*-
-;; if it doesn't have a .sisu extension.
-;;
-;; To handle .sisu files, e.g., 'filename.sisu', add something like
-;; (add-to-list 'auto-mode-alist '("\\.sisu$" . sisu-mode))
-;; to your .emacs file
-
-;;
-;; The documentation for the "Structure Of The Hierarchy Text" can be found in
-;; the sisustring for the sisu-mode function.

-SiSU Short Description
-</p>
-<p>
-SiSU is a comprehensive future-proofing electronic document management system.  Built-in search capabilities allow you to search across multiple documents and highlight matches in an easy-to-follow format.  Paragraph numbering system allows you to cite your electronic documents in a consistent manner across multiple file formats.  Multiple format outputs allow you to display your documents in plain text, PDF (portrait and horizontal), OpenDocument format, HTML, or e-book reading format (EPUB).  Word mapping allows you to easily create word indexes for your documents.  Future-proofing flexibility allows you to quickly adapt your documents to newer output formats as needed.  All these and many other features are achieved with little or no additional work on your documents - by marking up the documents with a super simplistic markup language, leaving the SiSU engine to handle the heavy-lifting processing.
-</p>
-<p>
-Potential users of SiSU include individual authors who want to publish their books or articles electronically to reach a broad audience, web publishers who want to provide multiple channels of access to their electronic documents, or any organizations which centrally manage a medium or large set of electronic documents, especially governmental organizations which may prefer to keep their documents in easily accessible yet non-proprietary formats.
-</p>
-<p>
-SiSU is an Open Source project initiated and led by Ralph Amissah <a href="mailto:ralph.amissah@gmail.com">&lt;ralph.amissah@gmail.com&gt;</a> and can be contacted via mailing list <a href="http://lists.sisudoc.org/listinfo/sisu">&lt;http://lists.sisudoc.org/listinfo/sisu&gt;</a> at <a href="mailto:sisu@lists.sisudoc.org">&lt;sisu@lists.sisudoc.org&gt;</a>.

-  For less markup than the most elementary HTML you can have more.
-</p>
-<p><a href="http://www.sisudoc.org/sisu/SiSU" target="_top"><b>SiSU</b> - Structured information, Serialized Units</a> for electronic documents, is an information structuring, transforming, publishing and search framework with the following features:</p>
-<p>
-<b>(i)</b> markup syntax:
-<b>(a)</b>
-simpler than html,
-<b>(b)</b>
-mnemonic, influenced by mail/messaging/wiki markup practices,
-<b>(c)</b> human readable, and easily writable,</p>
-<p><b>(ii)</b>
-<b>(a)</b>
-minimal markup requirement,
-<b>(b)</b>
-single file marked up for multiple outputs,</p>
-<p><b>
-notes
-</b></p>
-<p class="small">
-<b>*</b>
-documents are prepared in a single UTF-8 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>
-<p class="small">
-<b>*</b>
-markup is easily readable/parsed by the human eye, (basic markup is simpler and more sparse than the most basic html), [this may also be converted to XML representations of the same input/source document].

-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.
-</p>
-<p><b>(iii)</b>
-<b>(a)</b>
-multiple outputs primarily industry established and institutionally accepted open standard formats, include amongst others: plaintext (UTF-8); html; (structured) XML; ODF (Open Document text); EPUB; LaTeX; PDF (via LaTeX); SQL type databases (currently PostgreSQL and SQLite). Also produces: concordance files; document content certificates (md5 or sha256 digests of headings, paragraphs, images etc.) and html manifests (and sitemaps of content).

-<b>(b)
-</b>
-takes advantage of the strengths implicit in these very different output types, (e.g. PDFs produced using typesetting of LaTeX, databases populated with documents at an individual object/paragraph level, making possible granular search (and related possibilities))</p>
-<p><b>(iv)</b>
-outputs share a common numbering system (dubbed "object citation numbering" (ocn)) that is meaningful (to man and machine) across various digital outputs whether paper, screen, or database oriented, (PDF, html, XML, EPUB, sqlite, postgresql), this numbering system can be used to reference content.</p>
-<p>
-<b>(v)</b>
-SQL 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 hyperesteier].</p>
-<p>
-<b>(vi)</b>
- use of semantic meta-tags in headers permit the addition of semantic information on documents, (the available fields are easily extended)</p>
-<p>
-<b>(vii)</b>
-creates organised directory/file structure for (file-system) output, 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 (e.g. from an SQL search, you know where to go to find the prepared html output or PDF etc.)... there is more; easy directory management and document associations, the document preparation (sub-)directory may be used to determine output (sub-)directory, the skin used, and the SQL database used,</p>
-<p>
-<b>(viii)</b>
-"Concordance file" wordmap, consisting of all the words in a document and their (text/ object) locations within the text, (and the possibility of adding vocabularies),</p>
-<p>
-<b>(ix)</b>
-document content certification and comparison considerations:
-<b>(a)</b>
-the document and each object within it stamped with an md5 hash making it possible to easily check or guarantee that the substantive content of a document is unchanged,
-<b>(b)</b>
-version control, documents integrated with time based source control system, default RCS or CVS with use of $Id$ tag, which SiSU checks
-</p>
-<p>
-<b>(x)</b>
-SiSU's minimalist markup makes for meaningful "diffing" of the substantive content of markup-files,</p>
-<p>
-<b>(xi)</b>
-easily skinnable, document appearance on a project/site wide, directory wide, or document instance level easily controlled/changed,</p>
-<p>
-<b>(xii)</b>
-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,</p>
-<p>
-<b>(xiii)</b>
-prepared files may be batch process, documents produced are static files so 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>
-<p>
-<b>(xiv)</b>
-possible to pre-process, which permits: the easy creation of standard form documents, and templates/term-sheets, or; building of composite documents (master documents) from other sisu marked up documents, or marked up parts, i.e. import documents or parts of text into a main document should this be desired</p>
-<p>
-there is a considerable degree of future-proofing, output representations are "upgradeable", and new document formats may be added.
-</p>
-<p>
-<b>(xv)</b>
-there is a considerable degree of future-proofing, output representations are "upgradeable", and new document formats may be added:
-<b>(a)</b>
-modular, (thanks in no small part to Ruby) another output format required, write another module....
-<b>(b)</b> easy to update output formats (eg html, XHTML, LaTeX/PDF produced can be updated in program and run against whole document set),
-<b>(c)</b> easy to add, modify, or have alternative syntax rules for input, should you need to,</p>
-<p>
-<b>(xvi)</b>
-scalability, dependent on your file-system (ext3, Reiserfs, XFS, whatever) and on the relational database used (currently Postgresql and SQLite), and your hardware,</p>
-<p>
-<b>(xvii)</b>
-only marked up files need be backed up, to secure the larger document set produced,</p>
-<p>
-<b>(xviii)</b>
-document management,</p>
-<p>
-<b>(xix)</b>
-Syntax highlighting for SiSU markup is available for a number of text editors.</p>
-<p><b>(xx)</b> remote operations:
-<b>(a)</b>
-run SiSU on a remote server, (having prepared sisu markup documents locally or on that server, i.e. this solution where sisu is installed on the remote server, would work whatever type of machine you chose to prepare your markup documents on),
-<b>(b)</b>
-generated document outputs may be posted by sisu to remote sites (using rsync/scp)
-<b>(c)</b>
-document source (plaintext utf-8) if shared on the net may be identified by its url and processed locally to produce the different document outputs.</p>
-<p>
-<b>(xxi)</b>
-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 these too may be processed locally to produce the desired document outputs, these may be downloaded, shared as email attachments, or processed by running sisu against them, either using a url or the filename.
-</p>
-<p>
-<b>(xxii)</b>
-for basic document generation, the only software dependency is Ruby, and a few standard Unix tools (this covers plaintext, html, XML, ODF, EPUB, LaTeX). To use a database you of course need that, and to convert the LaTeX generated to PDF, a LaTeX processor like tetex or texlive.
-</p>
-<p>
-as a developers tool it is flexible and extensible

-SiSU ("SiSU information Structuring Universe" or "Structured information, Serialized Units"),<sup>1</sup> is a Unix command line oriented framework for document structuring, publishing and search. Featuring minimalistic markup, multiple standard outputs, a common citation system, and granular search.
-</p>
-<p class="tiny">
- Using markup applied to a document, SiSU can produce plain text, HTML, XHTML, XML, OpenDocument, LaTeX or PDF files, and populate an SQL database with objects<sup>2</sup> (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>
-
-<p class="small">
-How it works
-</p>
-<p class="tiny">
-SiSU markup is fairly minimalistic, it consists of: a (largely optional) document header, made up of information about the document (such as when it was published, who authored it, and granting what rights) and any processing instructions; and markup within text which is related to document structure and typeface. SiSU must be able to discern the structure of a document, (text headings and their levels in relation to each other), either from information provided in the instruction header or from markup within the text (or from a combination of both). Processing is done against an abstraction of the document comprising of information on the document's structure and its objects,<sup>2</sup> which the program serializes (providing the object numbers) and which are assigned hash sum values based on their content. This abstraction of information about document structure, objects, (and hash sums), provides considerable flexibility in representing documents different ways and for different purposes (e.g. search, document layout, publishing, content certification, concordance etc.), and makes it possible to take advantage of some of the strengths of established ways of representing documents, (or indeed to create new ones).</p>
-<p class="tiny">
-<sup>1.</sup> also chosen for the meaning of the Finnish term "sisu".
-</p>
-<p class="tiny">
-<sup>2</sup> 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>
-<p class="small">

-  <a href="http://www.sisudoc.org/sisu/SiSU/">
-    &lt;www.sisudoc.org/sisu/SiSU&gt;
-  </a>
-</p>
-<p class="tiny">
-SiSU was developed in relation to legal documents, and is strong across a wide variety of texts (law, literature...(humanities, law and part of the social sciences)). SiSU handles images but is not suitable for formulae/ statistics, or for technical writing at this time.</p>
-<p class="tiny">
-SiSU has been developed and has been in use for several years. Requirements to cover a wide range of documents within its use domain have been explored.</p>

-  end
-  def abstract
-    print <<WOK
-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.
-
-There is more detailed information available on it from:
-  #{@cX.blue}http://www.jus.uio.no/sisu#{@cX.off}
- *  plaintext
- *  html
- *  XML (structured)
- *  LaTeX/pdf
- *  texinfo
- *  sql (at present postgresql & sqlite)
-
-A couple of sample inputs and outputs:
-
-The markup for "War and Peace" (chosen because it is a large text & to test the use of SiSU on Project Gutenberg's plaintext), this is the markup, very little after the headers (there is an insert of their legal notices). Took no time at all, it is a particularly simple text to markup though
-A simple document                                                              and a more demanding document

-
- #{@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]

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

If -Z is used as the lone processing related flag (or in conjunction with a combination of -[mMvVq]), will remove the related document output directory.
-
- #{@cX.ruby}-z#{@cX.off} #{@cX.green}[filename/wildcard]#{@cX.off} produces php (zend) [feature disabled, depreciated]
-
- #{@cX.ruby}--harvest#{@cX.off} #{@cX.green}*.ss[tm]#{@cX.off} makes two lists of sisu output based on the sisu markup documents in a directory: list of author and authors works (year and titles), and; list by topic with titles and author.

-  #{@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}

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]

-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 either the form #{@cX.green}@headername:#{@cX.off} followed on the next line by an indented sub-category header if any #{@cX.green}:sub-headername:#{@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.

-   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) )

-  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):
-###

-      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):
-
-  1~  2~  3~  4~  5~  6~
-
-or, [0.38]
-
-  :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)
-
-eg.
-
-% SiSU 0.16 - 0.37
-
-1~ Document Title
-
-2~ Document Subtitle whatever it is
-
-3~ Part
-
-4~ Chapter
-
-5~ Heading
-
-6~ sub-heading
-
-in the 0.38 notation this maps to:
-
-% SiSU 0.38
-
-:A~ Document Title
-
-:B~ Document Subtitle whatever it is
-
-:C~ Part
-
-1~ Chapter
-
-2~ Heading
-
-3~ sub-heading
-
-(a conversion script provided in sisu-examples, modify.rb makes conversion between 0.37 and 0.38 markup simple)
-
-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, (0.38) alternative notation, A,B,C,1,2,3 mapping to 1,2,3,4,5,6
-
- SiSU has in effect two sets of levels to be considered
-
- 1-3 headings/levels, (A-C [0.38]) pre-ordinary paragraphs /pre-substantive text, and
-
- 4-6 headings/levels, (1-3 [0.38]) 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}~

-  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.
-
-  For information on download and installation, see #{@cX.blue}http://www.jus.uio.no/sisu/SiSU/download#{@cX.off}
-
-  For post installation help it is best you refer to '#{@cX.blue}man 8 sisu#{@cX.off}'
-
-  Host
-    host:             #{@cX.blue}#{@env.hostname}#{@cX.off}
-    arch:             #{@cX.blue}#{@env.arch}#{@cX.off}

-    data (document samples, images, README): #{@cX.blue}#{@env.path.sample_data}#{@cX.off}
-    processing:                              #{@cX.blue}#{@env.processing_path.processing}#{@cX.off}
-    output www:                              #{@cX.blue}#{@env.path.output}#{@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}
-
-  Install any additional programs of interest (that SiSU makes use of, that are not already on your system)
-
-    Programs SiSU makes use of include:
-      LaTeX
-      texinfo
-      pdfetex aka. pdflatex
-      sqlite
-      postgresql

-  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...

-* remote placement of sitemaps --sitemaps -R (probably makes more sense than doing against -Y [filename/wildcard]) - done but needs testing
-* gzip sitemaps - not before testing / after testing
-* issue with master documnts, naming and mapping, check multilingual

-      <<WOK
-
-  SiSU 0.57 (a subset of 1.0) is the same as 0.42 with the introduction of some
-  a shortcut to use the headers @title and @creator in the first heading
-  [expanded using the contents of the headers @title: and @author:]
-
-  :A~ @title by @author
-
-WOK
-    end
-    def sisu_0_42
-      <<WOK
-  SiSU 0.42 (a subset of 1.0) is the same as 0.38 with the introduction of some additional endnote types,
-
-  Introduces some varations on endnotes, in particular the use of the asterisk
-  ~{* for example for describing an author }~ and ~{** for describing a second author }~
-
-  * for example for describing an author
-
-  ** for describing a second author
-
-  and ~[* my note ]~ or ~[+ another note ]~ which numerically increments an
-  asterisk and plus respectively
-
-  *1 my note
-  +1 another note
-
-WOK
-    end
-    def sisu_0_38
-      <<WOK
-
-  SiSU 0.38 (a subset of 1.0) introduced alternative experimental header and heading/structure markers,
-
-  @headername: and headers :A~ :B~ :C~ 1~ 2~ 3~
-
-  as the equivalent of (the superceded)
-
-  0~headername and headers 1~ 2~ 3~ 4~ 5~ 6~
-
-  The internal document markup of SiSU 0.16 remains valid and standard
-  Though note that SiSU 0.37 introduced a new file naming convention
-
-  SiSU has in effect two sets of levels to be considered, using 0.38 notation
-  A-C headings/levels, pre-ordinary paragraphs /pre-substantive text, and
-  1-3 headings/levels, 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 may follow in sequence (not strict)
-      1 must exist, optional 2 and 3 may follow in sequence
-    i.e. there are two independent heading level sequences A,B,C and 1,2,3
-      (using the 0.16 standard notation 1,2,3 and 4,5,6)
-    on the positive side:
-      * the 0.38 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)
-      * the substantive text follows levels 1,2,3 and it is 'nice' to do
-        most work in those levels
-WOK
-    end
-    def sisu_0_37
-      <<WOK
-
-  SiSU 0.37 introduced the file naming convention, that remains in use in SiSU
-  v1 and v2, using the file extensions .sst .ssm and .ssi
-  to replace .s1 .s2 .s3 .r1 .r2 .r3  and .si
-
-  this is captured by the following file 'rename' instruction:
-
-  rename 's/\.s[123]$/\.sst/' *.s{1,2,3}
-  rename 's/\.r[123]$/\.ssm/' *.r{1,2,3}
-  rename 's/\.si$/\.ssi/' *.si
-
-  The internal document markup remains unchanged, from SiSU 0.16
-WOK
-    end
-    def sisu_0_16
-      <<WOK
-
-  SiSU 0.16 (0.15 development branch) introduced the use of
-
-  the header 0~ and headings/structure 1~ 2~ 3~ 4~ 5~ 6~
-
-  in place of the 0.1 header, heading/structure notation
