Only in Python 2.4 and later:

    starship:~> python2.3 -m this
    Unknown option: -m
    usage: python2.3 [option] ... [-c cmd | file | -] [arg] ...
    Try `python -h' for more information.

version "correct"?  I've been guilty myself on occasion, but I do try to
label my suggestions with version warnings.
