What I came up with is posted below. I'm quite surprised this

#Based on fpkg_list.pl by Steven J. Burr, part of the FinkCommander UI
for Fink.
#This script uses fink's perl subroutines to gather information on
#installed packages and print the data in a long list. The focus of
this script is to include
#Fink package categories along with specific information about the package.
