I have a server with shell and WebMin access.

I understand the directives in the virtual host section. What I don't
understand is how to set up ownership of the directories, I'll be
running perl scripts from a cgi-bin

/var/www/vhosts/some_domain/cgi-bin/ cgi-bin
/var/www/vhosts/some_domain/httpdocs/ web root

If someone could either give me step by step instructions (or point me
at a resource) of how to create the user and set up ownerships and
permissions I'd be very grateful. I'd like scripts to run from the
cgi-bin to have read/write access to the cgi-bin and webroot, but not
below (toward the root).

I've done a great deal of reading but I just get a snippet here and
there of how to do this, and when I put all that discombobulated
knowledge into action it's a mess!

I didn't see a more suited group, point me at one if you can't here.
