Indeed... that's what's supposed to happen. Who wants to call uprofile?
Who doesn't?

Atm, cd just changes dir as it is supposed to. Robert alerted us to the
fact that we can trigger a PRE_CMD on most shells when a CHANGEDIR
occurs.

This is the question... Call uprofile manually or detect the profile
automatically? Both capabilities? Mmm...

Yes and no. ~/.uselect/ contains a bin/ environment (prepended to your
PATH by /etc/profile or something) a env.d/ and most probabily
something else that gets executed uppon login.

This does not invalidate you having a ~/.uprofile/. uprofile will
configure your ~/.uselect/ and your environment variables. Your user
profile will not be interpreted by python, uprofile turns profile files
(from python) into bin/ and env.d/ environment on your ~/.uselect.

This may seem confusing, but that's the best way I can explain. Later
this weekend will send a call for ideas/call for modules to the dev
list to get everyone known with the uselect environment. I'm just
finishing cleaning up the code to start commiting and using git
branches.
