How do I know this? Fairly easy, go to the root of your Perl development tree on the box of your choice and append the results of 'grep -rd "^use " *.pl' to this:
#!/perl/bin/perl
#
# use.pl -- statistics for 'use' module name.
use strict;
use warnings;
use diagnostics;
my %module;
my @list;
while (<DATA>) {
if (/^use\s(.*?);/) {
my $what = $1;
if ($what =~ /^lib/) {
$module{'lib'}++;
}
elsif ($what =~ /^constant/) {
$module{'constant'}++;
}
else {
$module{$what}++;
}
}
}
for (keys %module) {
push(@list,sprintf("%04d|%s",$module{$_},$_));
}
for (sort @list) {
my($howmany,$what) = split /\|/;
print "$howmany, $what\n";
}
__DATA__
And then run the script...
--hsm
"Never try to teach a pig to sing...it wastes your time and it annoys the pig."

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).

or How to display code and escape characters
are good places to start.
