-# @(#)texi2html 1.52b 01/05/98 Written (mainly) by Lionel Cons, Lionel.Cons@cern.ch
-# 1.52a: Use acute accent instead of apostrophe. Add support for ISO-8859-1
-# characters with cedilla, circumflex etc.
-# 1.52b: Add option -expandtex. Expand @ifhtml by default, not @ifinfo.
-# Use Unicode quotation marks instead of grave and acute accents.
-# Emit charset=UTF-8 declaration.
-
# The man page for this program is included at the end of this file and can be
# viewed using the command 'nroff -man texi2html'.
