[BLUG] Sub domains in Apache

Hey blug'ers, I have a question for you. Does anyone have experience setting up sub-domains in Apache? Here's what I would like to happen.

Let's say with my domain wsams.org I would like to have say 3 sub-domains -- say linux, gentoo and mac.

I would like to have the setup where my home directory contains as many directories as I want, but as soon as I put the directory html inside one of those directories, that original directory becames a sub-domain.

The idea sould be to have

/home/wsams/linux/html   --->   http://linux.wsams.org
/home/wsams/gentoo/html   --->   http://gentoo.wsams.org
/home/wsams/mac/html   --->   http://mac.wsams.org

Also, the server should not have to be restarted. So say I create the directory

/home/wsams/foobar/html

I would have the sub-domain http://foobar.wsams.org

Does anyone know how to set this up easily. I just can't figure out what to search for.
