# Slackware build script for ircII

# Written by B. Watson (yalhcru@gmail.com)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# I don't know why nobody's already done a SlackBuild for this.
# Normally I prefer all-lowercase package names, but this just looks
# *wrong* as "ircii".

# 20210913 bkw:
# - update for v20210616. The datestamp comes from the output of
#   "ircII -v" (not the ChangeLog).
# - change DEFSRV to irc.libera.chat, now that freenode is a wasteland.
# - use a private libexec/ircII dir instead of binaries in /usr/libexec.
#   done because some other ircII-based client might conflict someday.
# - generate and include HTML docs.
# - add NOTES_TO_SELF to avoid cluttering up the script with comments.
# - correct and expand Debian's man pages.
# - add support for 'paranoid mode'.
# - have slack-desc show default server and paranoid mode.
