Perl has a command-line flag, -P (capital P), which sends its input script
through the C pre-processor before perl compilation. I can't
recall ever hearing of anybody actually using it, though it's
obviously there for a reason, and this sounds like as
good a reason as any. (Note that
perldoc perlrun warns, 'Because both comments and
cpp directives begin with the # character, you should
avoid starting comments with any words recognized by
the C preprocessor such as "if", "else", or "define".'
Also note that you can't define values on the command line;
-D sets debugger flags.)

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).
