#758: g3 f2py clean up
 Reporter:  pearu       |       Owner:  pearu
     Type:  task        |      Status:  new  
 Priority:  normal      |   Milestone:  1.2  
Component:  numpy.f2py  |     Version:  devel
 Severity:  normal      |    Keywords:       
 The development of g3 f2py tool is being moved to
 (see http://www.f2py.org/ for details). It means that

 1) numpy/f2py/lib directory can be removed after the move is complete.

 2) f2py script must be updated to use f2py package instead of
 numpy.f2py.lib when using the switch --g3-numpy.

 3) We also need a way to enable the g3 f2py tool for numpy.distutils. I
 can think
 of the following options:

 3.1) introduce environment variable F2PY than can hold strings 'g3-numpy',
 '2d-numpy', '2d-numeric', '2d-numarray' that determine which f2py backends
 will be used by numpy.distutils.

 3.2) introduce a function `use_f2py(<backend name>)` to numpy.distutils
 that can be used from setup.py files as well as from python session to set
 the f2py backend.

 The second option may be most appropiate.

 Both options have a problem of being global options. Theoretically, there
 may exist situations where different f2py backends must be used for
 different Fortran sources. The best solution would be to avoid such
 situations, meaning that g3 f2py must be backward compatible to
