Has anyone out there written PushDir and PopDir utilities?  These are CLI-
type utilities that I've gotten used to with MSDOS (At work OK?) and Unix.
They work like this:  You type "PushDir" and the current directory is saved
onto a stack.  You CD all over the place for a while, and when you want to
return to your original directory you type "PopDir".

If not, I'd like to take a stab at writing them.  I'm new to CLI internals
so I'd appreciate any help.  I assume the (or Shell) CLI has a lock on its
current directory.  When "PushDir" is called can I just duplicate this lock
in a data structure? When "PopDir" is called ,can I just Unlock the current
dir lock, and lock the saved lock?  (Heh heh.  Look at how naive I am).

Thanks for any help!
