Converting a perl/cgi site to WordPress

I have a site written in perl/cgi and SSI (server side includes) that I would like to move to WordPress.

Static pages shouldn’t be a problem and can be recreated in WP but there are also a number of custom perl/cgi scripts that I’d like to slowly move to WP/PHP as I can’t do it all at once.

The perl/cgi scripts can easily be stripped of any display markup to give the raw page content so is there an easy way of embedding these scripts into a WP page?

A plugin where I could use something like [includecgi /path/to/script.pl] would be perfect. I have looked through the plugins but not found anything.

Any help greatly appreciated. Thank you
