NAME
       f2py - Fortran to Python interface generator

SYNOPSIS
       (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) >

DESCRIPTION
       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.

OPTIONS
       -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 'unti-
	      tled'.

       --[no-]lower
	      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-signature
	      Overwrite existing signature file.

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

       --short-latex
	      Create 'incomplete' LaTeX document (without commands documentclass, 	ableofcontents, and egin{document}, end{document}).

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

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

       -include'<includefile>'
	      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.

       --[no-]wrap-functions
	      Create Fortran subroutine wrappers to Fortran 77 functions. --wrap-functions is default because it ensures maximum  portability/com-
	      piler independence.

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

       --quiet
	      Run quietly.

       --verbose
	      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.

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

       --help-compiler
	      List available Fortran compilers [DEPRECIATED].

       --fcompiler=<name>
	      Specify Fortran compiler type by vendor.

       --compiler=<name>
	      Specify C compiler type (as defined by distutils)

       --fcompiler-exec=<path>
	      Specify the path to F77 compiler [DEPRECIATED].

       --f90compiler-exec=<path>
	      Specify the path to F90 compiler [DEPRECIATED].

       --help-fcompiler
	      List available Fortran compilers and exit.

       --f77exec=<path>
	      Specify the path to F77 compiler.

       --f90exec=<path>
	      Specify the path to F90 compiler.

       --f77flags="..."
	      Specify F77 compiler flags.

       --f90flags="..."
	      Specify F90 compiler flags.

       --opt="..."
	      Specify optimization flags.

       --arch="..."
	      Specify architecture specific optimization flags.

       --noopt
	      Compile without optimization.

       --noarch
	      Compile without arch-dependent optimization.

       --debug
	      Compile with debugging information.

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

       --link-<resource>
	      Link  extension  module  with  <resource> as defined by numpy_distutils/system_info.py. 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

       -DPREPEND_FORTRAN -DNO_APPEND_FORTRAN -DUPPERCASE_FORTRAN -DUNDERSCORE_G77
	      Macros that might be required with non-gcc Fortran compilers.

       -DF2PY_REPORT_ATEXIT
	      To print out a performance report of F2PY interface when python exits. Available for Linux.

       -DF2PY_REPORT_ON_ARRAY_COPY=<int>
	      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.
