Quick clarifications:

- `--pylab` as a command-line flag is strongly discouraged and we will
likely remove it (having it in that location requires really awkward
special-case code everywhere).  But we'll probably keep the %pylab magic
indefinitely, since it's useful for quick-and-dirty command-line work where
you don't care about namespace pollution, just about minimizing typing and
namespace access for convenience.

- The %matplotlib magic can also be used without args, case in which it
works like %pylab used to, and will pick up the user's default backend:


In [1]: %matplotlib
Using matplotlib backend: TkAgg

In [2]: import matplotlib.pyplot as plt

In [3]: plt.plot([1,2,3])
Out[3]: [<matplotlib.lines.Line2D at 0x4b90ed0>]

Cheers
