True. For a standalone script, it's always nice to see some globally used parameters at the top for easy customization/configuration.
I do the follwing in such cases...
If the variables are "configuration" type of variables, I would use constants, not plain scalars. I feel much better in knowing that most ( if not all ) of the globally accessible variables would be visually different from other local variables:
#!perl
use constant LOG_DIRECTORY => '/foo/bar/baz';
use constant SOME_URL => 'http://baboon.com';
main();
sub main {
....
some_random_function( LOG_DIRECTORY, $local_variable );
}

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).
