In similar vein, I've found this little program surprisingly useful:
[~]$ cat `which pmwhich`
#!/usr/bin/perl
use warnings;
use strict;
die "pmwhich module-name\n" unless @ARGV == 1;
my $module = $ARGV[0];
$module =~ s!::!/!g;
for my $dir (@INC) {
my $fqn = "$dir/$module.pm";
if (-e $fqn) {
print $fqn, "\n";
last;
}
}
[~]$ pmwhich bigint
/usr/lib/perl5/5.8.5/bigint.pm
[~]$
It's a quick way to find out whether a particular module is installed -- and it helps me learn the tricks other module-writers have used. Shoulders of giants, y'know?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
