+### 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)
