# Slackware build script for irssi-python

# A note about the download URL: I'm stuck using the github
# auto-generated one, even though upstream created a static release
# tarball. Unfortunately, the release tarball is un-buildable because it's
# missing various files. Also it's missing the entire doc/ directory.

# VERSION is the irssi-python version, an underscore, and the irssi
# version we're building it for.
# Unfortunately we have to pick an irssi version to be the default,
# because the DOWNLOAD links are static (can't have $VERSION or such in
# them). This build will have to be updated any time Pat does an irssi
# version update.

# 20211208 bkw: update for vtest4_1.2.3.
