# DESCRIPTION :
#
# Executes some sort of find command specified in %find to locate a file
# then executes a command on the result of that find.
# e.g.
# 1> pmpath Text::Balanced
# /usr/local/lib/perl5/site_perl/5.6.1/Text/Balanced.pm
# 2> vi /usr/local/lib/perl5/site_perl/5.6.1/Text/Balanced.pm
#
# (or alternatively)
# 1> vi `pmpath Text::Balanced`
#
# becomes 
#
# 1> pvi Text::Balanced
# install this as e.g. wvi, then link other files to it.
# e.g.
#
# 1> ln -s wvi wless
# 2> ln -s wvi wls
# 3> ln -s wvi pwvi
#
# Add other lines into wvi to broaden the range of choices as needed.
# The pm utils are available from http://language.perl.com/misc/pmtools-1.00.tar.gz,
# including pmpath.
