This directory contains subclasses of devtest.os.TestCaseFactory. They are
meant to produce arrays of test cases, i.e. instances of implementations of the
abstract devtest.os.TestCase class. Think of a TestCaseFactory subclass as a
hook to define a specific file system / directory format. You can put your own
factory implementation either here and be done with it, or, alternatively,
anywhere in PYTHONPATH and add an import statement to devtest.os.TestCases.py.

TestCaseFactory instances' constructors are passed an array of file system
paths they should check for compatible test case definitions. The path array
could for instance be populated from the --test-case-path command line option,
a colon separated search path.
