# 20211019 bkw:
# - take over maintenance.
# - update for v3.3.
# - always docs/manpages, now that Slackware has rubygem-asciidoctor.
# - add doinst.sh, since we have .desktop and icons.
# - include old-style icon.
# - mention optional lua deps.
# - mention the fact that Tcl and Guile are supported scripting langs.
# - get rid of external stylesheets/fonts/JS in HTML docs, as this
#   is a privacy issue.

# I considered including the contents of Debian's weechat-scripts
# package here, but weechat's set up to download scripts from a remote
# server, not a local directory, so probly nobody'd ever use them.
