Just one more question: in the py3k-sympy directory I get after
running use2to3 I cannot run ./bin/isympy because of
File "./bin/isympy", line 175
print __doc__ # the docstring of this module above
^
SyntaxError: invalid syntax
I am far from being a Python expert, to say nothing of Python 2 vs 3,
but, as far as I remember, using print without parentheses is
forbidden in Python 3, so I gather that at least ./bin/isympy does not
get converted. Is this expected or am I missing something?
By the way, ./setup.py test runs nicely.
