#! /usr/bin/env python
# Convert GNU texinfo files into HTML, one file per node.
# Based on Texinfo 2.14.
# Usage: texi2html [-d] [-d] [-c] inputfile outputdirectory
# The input file must be a complete texinfo file, e.g. emacs.texi.
# This creates many files (one per info node) in the output directory,
# overwriting existing files of the same name. All files created have
# ".html" as their extension.
# XXX To do:
# - handle @comment*** correctly
# - handle @xref {some words} correctly
# - handle @ftable correctly (items aren't indexed?)
# - handle @itemx properly
# - handle @exdent properly
# - add links directly to the proper line from indices
# - check against the definitive list of @-cmds; we still miss (among others):
# - @defindex (hard)
# - @c(omment) in the middle of a line (rarely used)
# - @this* (not really needed, only used in headers anyway)
# - @today{} (ever used outside title page?)
# More consistent handling of chapters/sections/etc.
# Lots of documentation
# Many more options:
# -top designate top node
# -links customize which types of links are included
# -split split at chapters or sections instead of nodes
# -name Allow different types of filename handling. Non unix systems
# will have problems with long node names
# ...
# Support the most recent texinfo version and take a good look at HTML 3.0
# More debugging output (customizable) and more fexible error handling
# How about icons ?
