# Slackware build script for c_count

# 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. Annnoyingly enough, there's no man
# page for sloccount's c_count, and our man command is case-insensitive
# by default, so "man c_count" will show the man page for C_count since
# there isn't one for sloccount c_count. Confusing. Hopefully whoever
# this happens to, figures it out pretty quick.
