#  Note to the esteemed reader:
#
#  This file is a quick-start template perl script, meant to make it
#  easy to get a new script off the ground. It's _also_ quite
#  possible, therefore, that you're looking at a *descendant* of
#  "perl_template", which might explain certain oddities. (E.g., code
#  with variable names like):
#
#    my $Valopt = "default";
#    my $Boolopt = 0;
#
#  (or other cruft that seems to have nothing to do with the task at
#  hand, or incomplete usage information, and so on. Different script
#  based hereupon will be finished to different levels of goodness,
#  depending on the intended purpose, lifetime, audience, my whims,
#  and the time avialable for applying a spit-shine.
