Good, I'll take it.  ;-)

This isn't actually Zope specific; you can easily get the directory a module 
lives in using this:

    import os
    here = os.path.dirname(os.path.abspath(__file__))

The variable "here" will hold a string with an absolute path to the directory 
containing the source file for your module (named by __file__).  The call to 
os.path.abspath() isn't strictly necessary, but protects against future calls 
to os.chdir() (though not past calls!) in case the module was loaded from 
directory named by a relative directory on sys.path.

You can do this just once at module scope; there's no need to recompute this 
each time you need it.
