[mod_python] Getting mod_python version

Most modules have a __version__ member, and the help() built-in method
even looks for this variable and uses it to display the version of the
file:

>>>import cgi
>>>cgi.__version__
'2.6'
>>>help(cgi)
...skipping...
DATA
    __all__ = ['MiniFieldStorage', 'FieldStorage', 'FormContentDict',
'SvF...
    __version__ = '2.6'
    logfile = ''
    logfp = None
    maxlen = 0

VERSION
    2.6

>>>

I have not read or seen anything saying the "pythonic" way of versioning
a module is by try/except blocks testing to see if variable exist.  I
have however seen this from PEP 8:

Version Bookkeeping

    If you have to have RCS or CVS crud in your source file, do it as
    follows.

        __version__ = "$Revision: 1.20 $"
        # $Source: /cvsroot/python/python/nondist/peps/pep-0008.txt,v $

    These lines should be included after the module's docstring,
    before any other code, separated by a blank line above and
    below.

Which implies to me that __version__ is a pythonic way of versioning a
module/code file, though it doesn't seem to be as standard as __doc__.
