# Slackware build script for libnsgif

# Written by B. Watson (urchlay@slackware.uk)

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

# This build looks like it has no dependees, but graphics/imv lists it
# as an optional dep, so don't remove this just yet.

# 20230117 bkw: update for v0.2.1+20220113_105a920.
# - There are two libnsgif's on github, the original and the autotools-ized
#   one. This build is libnsgif-autotools, use correct repo in .info file
#   and git2tarxz.sh.
