+# Convert GNU texinfo files into HTML, one file per node.
+# Based on Texinfo 2.14.
+# Usage: texi2html [-d] [-d] 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):
+# - @set, @clear, @ifset, @ifclear
+# - @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?)
