I don't know of any such tool, but it could be done. I don't think it would solve the problem you refer to, though, which I understand as wanting to know where a given function actually comes from. One of the problems with creating a huge number of man pages for this is that function names may be duplicated; linspace, for example, could be coming from numpy or from mlab (until we get everything cleaned up...). So, I think you are stuck with two approaches: actually tracing imports back through the code, or running ipython, importing a module, and then using the ? facility: In [1]:import pylab In [2]:pylab.linspace? Type: function Base Class: <type 'function'> String Form: <function linspace at 0x8541a04> Namespace: Interactive File: /usr/local/lib/python2.5/site-packages/numpy/lib/function_base.py Definition: pylab.linspace(start, stop, num=50, endpoint=True, retstep=False) Docstring: Return evenly spaced numbers. Return num evenly spaced samples from start to stop. If endpoint is True, the last sample is stop. If retstep is True then return the step value used. Which shows that at present, the linspace supplied by pylab is actually the numeric version, not the mlab version. This is not at all obvious from looking at pylab.py!
