# Slackware build script for c_count

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

# 20251103 bkw: update for v6.25.
# 20250206 bkw: update for v7.24, rename binary to c-count.
# 20240807 bkw: update for v7.23.

# sloccount conflict is because both packages install /usr/bin/c_count.
# Upstream for c_count is aware of this but refuses to change (because
# his package is older). No idea if sloccount upstream knows or cares
# (it's been decades, so the problem isn't going to get solved). So
# install as c-count by default.
