Update link for dev_modules.php

I was going through this tutorial, http://fvwmforums.org/phpBB3/viewtopic.php?f=34&t=260 and came across this dead link]http://www.fvwm.org/documentation/dev_modules.php[/url]

I’m interested in reading though it if anybody could provide an updated link, please.

Maybe this will be similar

You may have to use the wayback machine to see what the old page was like, but I think this is the replacement.
