That doc describes all of the caveats for writing ePN plugins, the big ones being no named subs, no BEGIN/END blocks and close your files (as exit is never called). The output generated should be pretty short and readable even with a few chars fubarded on a alpha page. and the exit status codes (even though the table in the doco says the numerics) should be pulled out of util.pm (%ERRORS). -Waswas

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).
