Just to clarify, '-pylab' is  a very special switch, independent from
profiles, that does a bunch of things:

- read your matplotlib config to find your default backend
- configure ipython to work without blocking gui windows from matplotlib
- set matplotlib to interactive mode
- modify %run to play nicely with mpl
- import numpy and mpl names at the top level

You can have -pylab *and* a profile for personal customizations.
