Just a note on how to enable readline support for Mac, which isn’t included in the MGLtools distribution, but might be a nice addition at some point.
Readline will allow for recalling history via the up-arrow.
I seemed to have to install readline source for Python version 2.6 from, as 2.5 didn’t work: http://pypi.python.org/packages/source/r/readline/readline-2.6.1.tar.gz
then extract and run ‘python setup.py install’ and that’ll then say that your setuptools is out of date and will then automatically download and install a new version.
