-### texi2html customization script for LilyPond
-### Author: Reinhold Kainhofer <reinhold@kainhofer.com>, 2008.
-### Some code parts copied from texi2html and adapted. These functions
-### were written mainly by Patrice Dumas
-### License: GPLv2+
-###
-###
-### Features implemented here:
-### -) For split manuals, the main page is index.html.
-### -) All @unnumbered* sections are placed into the same file
-### (implemented by split_at_numbered_sections)
-### -) Use our custom CSS file, with IE-specific fixes in another CSS file,
-### impelmented by lilypond_css_lines
-### -) TOC (folded, with the current page highlighted) in an overflown <div>
-### is added to every page; implemented by:
-### lilypond_print_element_header -- building of the TOC
-### lilypond_toc_body -- generation of customized TOC output
-### lilypond_print_page_head -- start <div id="main">
-### print_lilypond_page_foot -- closing id=main, output of footer & TOC
-### -) External refs are formatted only as "Text of the node" (not as >>see
-### "NODE" section "SECTION" in "BOOK"<< like with default texi2html). Also,
-### the leading "(book-name)" is removed.
-### Implemented by overriding lilypond_external_ref
-### -) Navigation bars on top/bottom of the page and between sections are not
-### left-aligned, but use a combination of left/center/right aligned table
-### cells; For this, I heavily extend the texi2html code to allow for
-### differently aligned cells and for multi-line tables);
-### Implemented in lilypond_print_navigation
-### -) Different formatting than the default: example uses the same formatting
-### as quote.
-### -) Allow translated section titles: All section titles can be translated,
-### the original (English) title is associated with @translationof. This is
-### needed, because the file name / anchor is generated from the original
-### English title, since otherwise language-autoselection would break with
-### posted links.
-### Since it is then no longer possible to obtain the file name from the
-### section title, I keep a sectionname<=>filename/anchor around. This way,
-### xrefs from other manuals can simply load that map and retrieve the
-### correct file name for the link. Implemented in:
-### lilypond_unknown (handling of @translationof, in case
-### extract_texi_filenames.py messes up...)
-### lilypond_element_file_name (correct file name: use the map)
-### lilypond_element_target_name (correct anchor: use the map)
-### lilypond_init_map (read in the externally created map from disk)
-### lilypond_external_href (load the map for xrefs, use the correct
-### link target)
-### -) The HTML anchors for all sections are derived from the node name /
-### section title (pre-generated in the .xref-map file). Implemented by:
-### lilypond_element_target_name (adjust section anchors)
-### -) Use the standard footnote format "<sup>nr</sup> text" instead of the
-### ugly format of texi2html (<h3>(nr)</h3><p>text</p>). Implemented in
-### makeinfo_like_foot_line_and_ref
-### makeinfo_like_foot_lines
-### makeinfo_like_paragraph
-###
-###
-### Useful helper functions:
-### -) texinfo_file_name($node_name): returns a texinfo-compatible file name
-### for the given string $node_name (whitespace trimmed/replaced by -,
-### non-standard chars replaced by _xxxx (ascii char code) and forced to
-### start with a letter by prepending t_g if necessary)
