I was wondering about this shell idea I had.
The basic notion came from the fact that path manipulation is difficult.
For example, it's difficult (but can be done) to do a command like:
  ``Add this directory iff it's not already in the path''
or variations like:
  ``Add this directory iff it [and every parent directory] are protected
    from writing by anyone but root or bin''
This would be especially cool if it was one builtin command, IMHO.

You get the idea.  Is this a useful project?  Mail me any replies,
I'm a month or two behind on email (ick!)
