Just a small suggestion

[hetzbh]

The function RDocumentChRoot requires 2 parameters: one for the virtual directory "root" and the other is the actual real directory.

My suggestion: How about using something like this - if the line only includes 1 parameter, then ruid2 will treat it as root, so for example:

RDocumentChRoot /home/mysite/public_html

That way, the / will redirect to /home/mysite/public_html/ and if the user will put 2 parameters, it will behave as it is today.

What do you think?
