There are actually only 3 modules (+2 by mistake) in all of NumPy that have
listings if I counted correctly. If you think those are useful maybe we can
make it an optional section (i.e. they should not be deleted, but most
modules don't need them)?

In NumPy, the ones with listings are:
- numerictypes
- fftpack
- arraysetops
- random (accidental copy of random.info)
- linalg (accidental copy of linalg.info)

In addition there are a few large modules with listings in separate info
files:
- core
- lib
- random
- linalg
- fft

In SciPy listings for modules (stats, interpolate, integrate, special, ...)
also reside in info files.

Cheers,
Ralf
