A module is a .pm file containing some Perl code. A package is a declaration of the name of the current scope, e.g.:
package Math::Complex
which can occur in the code of a module or a script. A module can be used, because it is a physical 'thing', but a package cannot. A module may contain several packages: CPAN does this. The advantage is that the code inside that module can still be chunked up into classes/etc. by package declarations, as if these classes were separate modules, but that the functionality is still lumped into a single convenient file.

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).
