# Revision 1.10 1994/12/28 20:10:25 seth
# * Added --extract, etc.
#
# Revision 1.9 94/12/13 15:16:23 15:16:23 seth (Seth Golub)
# * Changed from #!/usr/local/bin/perl to the more clever version in
# the man page. (How did I manage not to read this for so long?)
# * Swapped hrule & header back to handle double lines. Why should
# this order screw up headers?
#
# Revision 1.8 1994/11/30 21:07:03 seth
# * put mail_anchor back in. (Why did I take this out?)
# * Finally added handling of lettered lists (ordered lists marked with
# letters)
# * Added title option (--title, -t)
# * Shortline now looks at how long the line was before txt2html
# started adding tags. ($line_length)
# * Changed list references to scalars where appropriate. (@foo[0] -> $foo[0])
# * Added untabify() to homogenize leading indentation for list
# prefixes and functions that use line length
# * Added "underline tolerance" for when underlines are not exactly the
# same length as what they underline.
# * Added error message for unrecognized options
# * removed \w matching on --capstag
# * Tagline now removes leading & trailing whitespace before tagging
# * swapped order of caps & heading in main loop
# * Cleaned up code for speed and to get rid of warnings
# * Added more restrictions to something being a mail header
# * Added indentation for lists, just to make the output more readable.
# * Fixed major bug in lists: $OL and $UL were never set, so when a
# list was ended "</UL>" was *always* used!
# * swapped order of hrule & header to properly handle long underlines
#
# Revision 1.7 94/10/28 13:16:11 13:16:11 seth (Seth Golub)
# * Added to comments in options section
# * renamed blank to is_blank
# * Page break is converted to horizontal rule <HR>
# * moved usage subroutine up top so people who look through code see
# it sooner
#
# Revision 1.6 94/10/28 12:43:46 12:43:46 seth (Seth Golub)
# * Creates anchors at each heading
#
# Revision 1.5 94/07/14 17:43:59 17:43:59 seth (Seth Golub)
# * Fixed minor bug in Headers
# * Preformatting can be set to only start/stop when TWO lines of
# [non]formatted-looking-text are encountered. Old behavior is still
# possible through command line options (-pb 1 -pe 1).
# * Can preformat entire document (-pb 0) or disable preformatting
# completely (-pe 0).
# * Fixed minor bug in CAPS handling (paragraph breaks broke)
# * Puts paragraph tags *before* paragraphs, not just between them.
#
# Revision 1.4 94/06/20 16:42:55 16:42:55 seth (Seth Golub)
# * Allow ':' for numbered lists (e.g. "1: Figs")
# * Whitespace at end of line will not start or end preformatting
# * Mailmode is now off by default
# * Doesn't break short lines if they are the first line in a list
# item. It *should* break them anyway if the next line is a
# continuation of the list item, but I haven't dealt with this yet.
# * Added action on lines that are all capital letters. You can change
# how these lines get tagged, as well as the mininum number of
# consecutive capital letters required to fire off this action.
#
# Revision 1.3 94/05/17 15:58:58 15:58:58 seth (Seth Golub)
# * Tiny bugfix in unhyphenation
#
# Revision 1.2 94/05/16 18:15:16 18:15:16 seth (Seth Golub)
# * Added unhyphenation
#
# Revision 1.1 94/05/16 16:19:03 16:19:03 seth (Seth Golub)
# Initial revision
#
#
# 1.02 Allow '-' in mail headers
# Added handling for multiline mail headers
