skipdoctest.py

"""Decorators marks that a doctest should be skipped, for both python 2 and 3.

The IPython.testing.decorators module triggers various extra imports, including
numpy and sympy if they're present. Since this decorator is used in core parts
of IPython, it's in a separate module so that running IPython doesn't trigger
those imports."""
