The CGI Wrap script creates a scgi-bin folder at the public_html level of your web site. This allows you to run scripts with your own user ID.

The advantage of this is that you can run scripts that have the same permissions that you do - you can write, edit, and delete files as you normally do. In a regular cgi-bin folder, you can only do this if you set your directory permissions to 777 (world access) and file permissions to 666, both of which are quite dangerous as anyone can now modify your web site.

The disadvantage of this is that if there is a security breach in your script that another person can exploit, they have access to your site in the same manner that you do - they can do anything. However, as long as the scripts you run in the scgi-bin directory are secure, you have nothing to worry about.
