# Converted to use new pkgbase() function to remove pathname and
# valid package extensions.
#
# Wed Oct 31 16:28:46 CDT 2007
#  * Thanks to Gabriele Inghirami for a patch allowing this script to work
#    with much larger numbers of installed packages.
# Wed, 27 Apr 1994 00:06:50 -0700 (PDT)
#  * Optimization by David Hinds.
# Sun Oct 24 23:11:40 BST 2004
#  * Further optimisations by Jim Hawkins <jawkins@armedslack.org>
#    - dramatically improved the speed of the "View" option
# Thu Nov 04 12:19:56 BST 2004
#  * More optimisations by Jim Hawkins
#    - improved "Remove" speed in a similar manner to "View"
# Wed Jan 12 16:53:48 GMT 2005
#  * Fixed quoting bug thanks to Lasse Collin
# Wed Jan 26 23:06:22 GMT 2005
#  * Fix for non-standard package descriptions by Jim Hawkins
