The swcgi script is used to be able to use Apache and SkunkWeb together without the use of mod_skunkweb. Specifically, in cases where you're not allowed to install Apache modules, or things of that nature.
A typical configuration would be to add the following to your httpd.conf:
ScriptAlias / /usr/local/skunk/bin/swcgi
To really use it though you should check out the top of the script and edit it to suit your needs (right now, the thing to check out is the value of the connectInfo variable).
