# v1 -- 20aug95
# v2 -- 2oct95   [improved it]
# v3 -- 17mar96  [fixed it up for 1.0 multi-channel]
# v4 -- 3nov97  [Fixed it up for 1.3.0 version bots] by TG
# v4.00001 nov97 [blurgh]
# v5-BETA1 -- 26sep99 by rtc
#
# o clean webfile var removal
# o using timezone variable from config file
# o unified options and removed unnecessary ones.
# o convert urls, nicks etc. to HTML before we put them into the page.
# o nice html source indenting
# o replace the old file after the new one has completely written to
#   disk
# o the description still contained robey's address, replaced
#   by the eggheads email.
# o don't link any spaces in the HTML2.0 file
# v5-RC1 -- 29sep99 by rtc
# o info line wasn't converted to HTML.
# o now supports bold, italic and underline text style and colors.
# v5-FINAL -- 04oct99 by rtc
# o style converter now strictly follows HTML standard.
# o Fake color attributes with number > 2^32 don't cause Tcl
#   error anymore.
# o now uses strftime as time and date functions have both been removed
#   in 1.3.29

# this will create an html file every so often (the default is once every
# 5 minutes).  the html file will have a table showing the people currently
# on the channel, their user@hosts, who's an op, and who's idle.  it
# uses a table which some browsers (and pseudo-browsers like lynx) can't
# see, but it can optionally make a second page which will support these
# archaic browsers.  browsers supporting push-pull will receive the updated
# page automatically periodically.
#
# if you have a "url" field defined for a user, their nickname in the
# table will be a link pointing there.  otherwise it checks the info
# line and comment field to see if they start with "http://" -- if so,
# that link will be used.  as a last resort, it will make a "mailto:"
# link if an email address is recorded for the user.
#
# feel free to modify and play with this.  the original was written in
# 15 minutes, then at various times i fixed bugs and added features.
# softlord helped me make the design look a little nicer. :)  if you make
# any nifty improvements, please let us know.
