def __init__(self, verbose=False, parser=DocTestParser(),<EOL>recurse=True, _namefilter=None, exclude_empty=True):

Create a new doctest finder.

The optional argument `parser` specifies a class or
function that should be used to create new DocTest objects (or
objects that implement the same interface as DocTest).  The
signature for this factory function should match the signature
of the DocTest constructor.

If the optional argument `recurse` is false, then `find` will
only examine the given object, and not any contained objects.

If the optional argument `exclude_empty` is false, then `find`
will include tests for objects with empty docstrings.
