# I can't figure out how to include this in the main script and have the
# globbing functions *work* -- (e.g. include shopt -s and use the +([^-])
# stuff below - bash doesn't like it).
#
# This is particularly useful for KDE.SlackBuild and x11.SlackBuild since
# some packages have the same package name prefix - xcb-util- for example.
#
# To use this script from another:
# ensure PKGNAM, PKGSERIES and PKGSTORE are set and then call it directly
# /usr/share/slackdev/slackwipepkg
#
shopt -s extglob # needed to find package names
