F2PY - Fortran to Python Interface Generator

I am pleased to announce the seventh public release of F2PY, version
2.39.235_1642. The purpose of the F2PY project is to provide the 
connection between Python and Fortran programming languages.

What's new?

Since the last public release, that was more than two years ago, F2PY
project has been actively maintained and many useful features have been
implemented. Here follows some highlights:

* New statement ``usercode`` allows inserting user defined C code to F2PY
  generated extension module sources at various relevant places: before
  wrapper functions, after variable declarations, and to the end of
  initialization function of the module. This makes using F2PY very

* New statement ``pymethoddef`` allows adding items to PyMethodDef-array.

* Full support for character arrays and arrays of strings is finally

* Number of feature requests from users are implemented. For example:
  - the auxiliary ``as_column_major_storage()`` that efficiently converts
    array to column storage order
  - the F2PY_REPORT_ON_ARRAY_COPY macro that when defined sends a message
    to stderr when copy of an array with the size larger than specified
    threshold is made.
  - Numarray support, thanks to Todd Miller.

* Support for Win32 and Mac OSX platforms is considerably improved. The
  list of compilers supported by the scipy_distutils package is longer
  than ever:
    GNU Fortran Compiler
    Portland Group Fortran Compiler
    Absoft Corp Fortran Compiler
    MIPSpro Fortran Compiler
    Sun|Forte Fortran 95 Compiler
    Intel Fortran Compiler for 32-bit apps
    Intel Visual Fortran Compiler for 32-bit apps
    Intel Fortran Compiler for Itanium apps
    NAGWare Fortran 95 Compiler
    Compaq Fortran Compiler
    DIGITAL|Compaq Visual Fortran Compiler
    Pacific-Sierra Research Fortran 90 Compiler
    HP Fortran 90 Compiler
    Lahey/Fujitsu Fortran 95 Compiler
    IBM XL Fortran Compiler

* Numerous bugs are fixed. You should definitely update F2PY when using
  complex input arrays, there was a nasty bug that in certain cases
  caused incorrect results.

* F2PY has now a man page and its documentation is kept up to date. Many
  other improvements to F2PY algorithm and usage are implemented, see
  HISTORY.txt for more details.
