The *biggest* single optimisation for space that you could make is not
to have both .pyc and .pyo files. AFAIK, the only difference between
the two now is that .pyo files don't have asserts included. Testing on
build 625 of the OLPC runnng in VMWare, that removes about 3MB from
the numpy package right there (and even more when done globally --
about 25MB.). [btw, the Python test/ directory would be another 14MB.]
After that,
1) remove f2py -- as you say, no Fortran, no need (2.2MB)
2) remove test directories "find . -name tests -type d -exec rm -rf
{} ;' (1MB)
3) remove distutils (1MB)
Now, it's down to about 3.5 MB; there's not much more that can be done
after that.
While I'm confident that removing the f2py and test directories can be
done safely (by just removing the directories), I'm not so sure about
numpy.distutils -- it really depends on what other software you're
using. It could be trimmed a bit: the Fortran compiler descriptions in
distutils/fcompiler/ could be removed, and system_info.py could be cut
down. Although you can make up for the extra space it uses by removing
Numeric (2MB).
