-Cython-compatible wrapper for doctest.testmod().
-
-Usage example, assuming a Cython module mymod.pyx is compiled.
-This is run from the command line, passing a command to Python:
-python -c "import cydoctest, mymod; cydoctest.testmod(mymod)"
-
-(This still won't let a Cython module run its own doctests
-when called with "python mymod.py", but it's pretty close.
-Further options can be passed to testmod() as desired, e.g.
-verbose=True.)
