--- BEGIN ISSUE ---
MAINT: remove numpy/tools/test-installed-numpy.py ?
Looking at Matti's modifications in #13482, I don't see a good reason to keep `test-installed-numpy.py` if we are going to continue using `runtests.py`. Both have separate parsers to accomplish similar things, but `runtests.py` is more developed / actively used while `test-installed-numpy.py` still has discussion of nose / python 2.4, and Matti's proposed change there adds `-n` option which does something different in `runtests.py`.

`runtests.py -n` will test installed NumPy instead of rebuilding, so seems like redundancy / maintenance burden we don't need moving forward
