.SH NAME
f2py \- Fortran to Python interface generator
.SH SYNOPSIS
(1) To construct extension module sources:

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

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

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

(3) To generate signature files:

.B f2py
-h <filename.pyf> ...< same options as in (1) >
.SH 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.
.SH OPTIONS
.TP
.B \-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.
.TP
.B <fortran functions>
Names of fortran routines for which Python C/API functions will be
generated. Default is all that are found in <fortran files>.
.TP
.B skip:
Ignore fortran functions that follow until `:'.
.TP
.B only:
Use only fortran functions that follow until `:'.
.TP
.B :
Get back to <fortran files> mode.
.TP
.B \-m <modulename>
Name of the module; f2py generates a Python/C API file
<modulename>module.c or extension module <modulename>.  Default is
\'untitled\'.
.TP
.B \-\-[no\-]lower
Do [not] lower the cases in <fortran files>. By default, \-\-lower is
assumed with \-h key, and \-\-no\-lower without \-h key.
.TP
.B \-\-build\-dir <dirname>
All f2py generated files are created in <dirname>. Default is tempfile.mktemp().
.TP
.B \-\-overwrite\-signature
Overwrite existing signature file.
.TP
.B \-\-[no\-]latex\-doc
Create (or not) <modulename>module.tex.  Default is \-\-no\-latex\-doc.
.TP
.B \-\-short\-latex
Create 'incomplete' LaTeX document (without commands \\documentclass,
\\tableofcontents, and \\begin{document}, \\end{document}).
.TP
.B \-\-[no\-]rest\-doc
Create (or not) <modulename>module.rst.  Default is \-\-no\-rest\-doc.
.TP
.B \-\-debug\-capi
Create C/API code that reports the state of the wrappers during
runtime. Useful for debugging.
.TP
.B \-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.
.TP
.B \-\-[no\-]wrap\-functions
Create Fortran subroutine wrappers to Fortran 77
functions. \-\-wrap\-functions is default because it ensures maximum
portability/compiler independence.
.TP
.B \-\-help\-link [..]
List system resources found by system_info.py. [..] may contain
a list of resources names. See also \-\-link\-<resource> switch below.
.TP
.B \-\-quiet
Run quietly.
.TP
.B \-\-verbose
Run with extra verbosity.
.TP
.B \-v
Print f2py version ID and exit.
.TP
.B \-\-include_paths path1:path2:...
Search include files (that f2py will scan) from the given directories.
.SH "CONFIG_FC OPTIONS"
The following options are effective only when \-c switch is used.

Specify the path to F77 compiler.
.TP
.B \-\-f90exec=<path>
Specify the path to F90 compiler.
.TP

Specify architecture specific optimization flags.
.TP
.B \-\-noopt
Compile without optimization.
.TP
.B \-\-noarch
Compile without arch-dependent optimization.

.SH "EXTRA OPTIONS"
The following options are effective only when \-c switch is used.
.TP
.B \-\-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.

.TP
.B -L/path/to/lib/ -l<libname>
.TP
.B -D<define> -U<name> -I/path/to/include/ 
.TP
.B <filename>.o <filename>.so <filename>.a

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

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

.TP
.B -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.

.SH REQUIREMENTS
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).
