"""Utility routines depending on the finder,
a combination of code by Jack Jansen and erik@letterror.com.

Most events have been captured from
Lasso Capture AE and than translated to python code.

IMPORTANT
Note that the processes() function returns different values
depending on the OS version it is running on. On MacOS 9
the Finder returns the process *names* which can then be
used to find out more about them. On MacOS 8.6 and earlier
the Finder returns a code which does not seem to work.
So bottom line: the processes() stuff does not work on < MacOS9
