I never remember how to recursively add files to perforce. This page describes a command to do it.
On the Linux/Mac OS X p4 command line tool this is the command:
find . -type f -print | p4 -x - add
Cool, I didn't know about the -x. I find myself doing this often at work:find . -type f | xargs p4 add
on windowsdir /s/b *.* | p4 -x - add
