# Even with the patch below, checkinstall does not do a perfect job building
# Slackware packages.  For example, bin directories (and binaries in them) aren't
# chowned root:bin as the FSSTND recommends.  Of course, this is purely cosmetic
# anyway.  This patch causes checkinstall to use the native Slackware package
# building tool, though, and allows us to meet the "good enough" standard of
# excellence.  ;-)
