A couple of comments on pod2usage, um, usage :)
Since pod2usage by default exits, your explicit exit calls are redundant at best and confusing at worst. This
pod2usage(-verbose => 1) && exit if defined $opt_help;
is the same as this:
pod2usage(-verbose => 1) if defined $opt_help;
You could also take advantage of the -message option. This
print "$0: input_file required\n";
pod2usage(-verbose => 0) && exit
is the same as this:
pod2usage(-verbose => 0, -message => "$0: input_file required\n")
A comment on Getopt::Long usage: instead of declaring several separate $opt_XXX scalar variables, it might be more natural Storing options values in a hash.

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.
