# Slackware build script for irssi_otr

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

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

# 20150510 bkw:
# - updated for 1.0.0.
# - 1.0.0 uses libotr-4.x, so rip out all the static linking mess.
# - upstream switched from cmake to autoconf, rewrite most of script.
# - xchat support was dropped by upstream, so remove all references.

# 20150907 bkw:
# - handle case where file was saved as v1.0.0.tar.gz

# 20160727 bkw:
# - updated for 1.0.1.
# - use --with-irssi-module-dir now that it exists.
# - add patch to deal with newer irssi's module ABI version check.
