# This is an extension file for the excellent `texi2html' utility by
# Lionel Cons.  See <http://wwwcn.cern.ch/dci/texi2html/> for more
# information on `texi2html'.

# `texi2html' will include any file (like this one) named
# `texi2html.ext' in the directory in which it is run.

# This extension file causes URLs marked as @file{} style to be
# converted to true hyperlinks.  Well, some URLs, some non-URLs; close
# enough for the Mailcrypt manual.

$URLRE = '^(http)|(ftp)|(news):'; # RE for a URL.  Woefully
				  # incomplete, but adequate.
