       f2py - Fortran to Python interface generator


       (1) To construct extension module sources:

       f2py  [<options>]  <fortran  files>  [[[only:]||[skip:]] <fortran functions> ] [: <fortran
       files> ...]

       (2) To compile fortran files and build extension modules:

       f2py -c [<options>, <config_fc options>, <extra options>] <fortran files>

       (3) To generate signature files:

       f2py -h <filename.pyf> ...< same options as in (1) >


       This program generates a Python C/API file (<modulename>module.c) that  contains  wrappers
       for  given  Fortran  or  C  functions so that they can be called from Python.  With the -c
       option the corresponding extension modules are built.


       -h <filename>
              Write signatures of the fortran routines to file <filename> and exit. You can  then
              edit  <filename>  and use it instead of <fortran files>. If <filename>==stdout then
              the signatures are printed to stdout.

       <fortran functions>
              Names of fortran routines for which  Python  C/API  functions  will  be  generated.
              Default is all that are found in <fortran files>.

       skip:  Ignore fortran functions that follow until `:'.

       only:  Use only fortran functions that follow until `:'.

       :      Get back to <fortran files> mode.

       -m <modulename>
              Name  of  the  module;  f2py  generates a Python/C API file <modulename>module.c or
              extension module <modulename>.  Default is ´untitled´.

              Do [not] lower the cases in <fortran files>. By default, --lower is assumed with -h
              key, and --no-lower without -h key.

       --build-dir <dirname>
              All f2py generated files are created in <dirname>. Default is tempfile.mktemp().

              Overwrite existing signature file.

              Create (or not) <modulename>module.tex.  Default is --no-latex-doc.

              Create    'incomplete'    LaTeX    document   (without   commands   \documentclass,
              \tableofcontents, and \begin{document}, \end{document}).

              Create (or not) <modulename>module.rst.  Default is --no-rest-doc.

              Create C/API code that reports the state of the wrappers during runtime. Useful for

              Add  CPP  #include  statement  to  the  C/API code.  <includefile> should be in the
              format of either `"filename.ext"' or `<filename.ext>'.  As a  result  <includefile>
              will  be  included just before wrapper functions part in the C/API code. The option
              is depreciated, use `usercode` statement in signature files instead.

              Create Fortran subroutine wrappers to Fortran  77  functions.  --wrap-functions  is
              default because it ensures maximum portability/compiler independence.

       --help-link [..]
              List system resources found by [..] may contain a list of resources
              names. See also --link-<resource> switch below.

              Run quietly.

              Run with extra verbosity.

       -v     Print f2py version ID and exit.

       --include_paths path1:path2:...
              Search include files (that f2py will scan) from the given directories.


       The following options are effective only when -c switch is used.

              List available Fortran compilers [DEPRECIATED].

              Specify Fortran compiler type by vendor.

              Specify C compiler type (as defined by distutils)

              Specify the path to F77 compiler [DEPRECIATED].

              Specify the path to F90 compiler [DEPRECIATED].

              List available Fortran compilers and exit.

              Specify the path to F77 compiler.

              Specify the path to F90 compiler.

              Specify F77 compiler flags.

              Specify F90 compiler flags.

              Specify optimization flags.

              Specify architecture specific optimization flags.

              Compile without optimization.

              Compile without arch-dependent optimization.

              Compile with debugging information.


       The following options are effective only when -c switch is used.

              Link extension module with <resource> as defined by numpy_distutils/
              E.g.  to  link with optimized LAPACK libraries (vecLib on MacOSX, ATLAS elsewhere),
              use --link-lapack_opt. See also --help-link switch.

       -L/path/to/lib/ -l<libname>

       -D<define> -U<name> -I/path/to/include/

       <filename>.o <filename>.so <filename>.a

              Macros that might be required with non-gcc Fortran compilers.

              To print out a performance report of F2PY interface when  python  exits.  Available
              for Linux.

              To  send  a  message  to  stderr  whenever F2PY interface makes a copy of an array.
              Integer <int> sets the threshold for array sizes when a message should be shown.


       Python 1.5.2 or higher (2.x is supported).

       Numerical Python 13 or higher (20.x,21.x,22.x,23.x are supported).

       Optional Numarray 0.9 or higher partially supported.
