Also, take a look at this:
#!/usr/bin/perl -s
use strict;
our $h;
if ($h) {
print "this is a very special feature";
}
The -s switch "interprets -xxx on the command line as a switch and sets
the corresponding variable $xxx in the script to 1." There's also
something else, which I leave for you to discover... ;-) You know what
they say, "man perlrun"!! :-)
I usually use something like this, actually:
die "this is the help text
blah blah blah
" if $h;
