# 20200811 bkw: fix various issues on behalf of the SBo team:
# - man pages were in /usr/share/man
# - old source wasn't being deleted before extraction
# - removed "-GNinja" from cmake command line: unnecessary, and adds a
#   dependency on ninja (which wasn't listed in the .info file)
# - got rid of unneeded template code (no perllocal.pod gets installed)
# - move binary to /usr/games (since it has a section 6 man page)
