# Modified to handle either old 8.3 or new package-version-arch-build.tgz
# packages, Sat Nov 17 14:25:58 PST 2001 volkerdi
#
# Rewritten to clean out _all_ old packages of a given basename, not just
# the first one found, Thu Apr 4 01:01:05 PST 2002 volkerdi
#
# Added --install-new and --reinstall, Fri May 31 14:11:14 PDT 2002 volkerdi
# Added --dry-run, Sat Apr 26 18:13:29 PDT 2003
#
# Sat Apr 25 21:18:53 UTC 2009
# Support new compression types and package extensions.
# Converted to use new pkgbase() function to remove pathname and
# valid package extensions.
#
# Sat 17 Jan 16:21:32 UTC 2015 mina86
# Various optimisation mostly resolving around avoiding having to fork
# and call cut, basename and other helper commands. Slight
# refactoring of code calling removepkg.
