+        Fortran source of module / subroutine to compile
+
+        .. versionchanged:: 1.16.0
+           Accept str as well as bytes
+
+    modulename : str, optional

+    extra_args : str or list, optional
+        Additional parameters passed to f2py

+            A list of args may also be provided.

+    verbose : bool, optional
+        Print f2py output to screen
+    source_fn : str, optional
+        Name of the file where the fortran source is written.
+        The default is to use a temporary file with the extension
+        provided by the `extension` parameter
+    extension : {'.f', '.f90'}, optional
+        Filename extension if `source_fn` is not provided.

+        This function is not needed when building an extension with
+        `numpy.distutils` directly from ``.f`` and/or ``.pyf`` files
+        in one go.
+
+    Python extension modules built with f2py-generated code need to use
+    ``fortranobject.c`` as a source file, and include the ``fortranobject.h``
+    header. This function can be used to obtain the directory containing

+    -------
+    include_path : str

+
+    Notes
+    -----
+    .. versionadded:: 1.22.0
+
+    Unless the build system you are using has specific support for f2py,
+    building a Python extension using a ``.pyf`` signature file is a two-step
+    process. For a module ``mymod``:
+
+        - Step 1: run ``python -m numpy.f2py mymod.pyf --quiet``. This
+          generates ``_mymodmodule.c`` and (if needed)
+          ``_fblas-f2pywrappers.f`` files next to ``mymod.pyf``.
+        - Step 2: build your Python extension module. This requires the
+          following source files:
+
+              - ``_mymodmodule.c``
+              - ``_mymod-f2pywrappers.f`` (if it was generated in step 1)
+              - ``fortranobject.c``

+
+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>, <build_flib 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 functions so that they
+             can be called from Python. With the -c option the corresponding
+             extension modules are built.
+
+Options:
+
+  --2d-numpy       Use numpy.f2py tool with NumPy support. [DEFAULT]
+  --2d-numeric     Use f2py2e tool with Numeric support.
+  --2d-numarray    Use f2py2e tool with Numarray support.
+  --g3-numpy       Use 3rd generation f2py from the separate f2py package.
+                   [NOT AVAILABLE YET]
+
+  -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>.
+  <fortran files>  Paths to fortran/signature files that will be scanned for
+                   <fortran functions> in order to determine their signatures.
+  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'.
+
+  --[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.mkdtemp().
+
+  --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, \\tableofcontents, and \\begin{{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.
+
+  --[no-]wrap-functions    Create Fortran subroutine wrappers to Fortran 77
+                   functions. --wrap-functions is default because it ensures
+                   maximum portability/compiler independence.
+
+  --include-paths <path1>:<path2>:...   Search include files from the given
+                   directories.
+
+  --help-link [..] List system resources found by system_info.py. See also
+                   --link-<resource> switch below. [..] is optional list
+                   of resources names. E.g. try 'f2py --help-link lapack_opt'.
+
+  --f2cmap <filename>  Load Fortran-to-Python KIND specification from the given
+                   file. Default: .f2py_f2cmap in current directory.
+
+  --quiet          Run quietly.
+  --verbose        Run with extra verbosity.
+  -v               Print f2py version ID and exit.
+
+
+numpy.distutils options (only effective with -c):
+
+  --fcompiler=         Specify Fortran compiler type by vendor
+  --compiler=          Specify C compiler type (as defined by distutils)
+
+  --help-fcompiler     List available Fortran compilers and exit
+  --f77exec=           Specify the path to F77 compiler
+  --f90exec=           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 (only effective with -c):
+
+  --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.

+  Using the following macros may be required with non-gcc Fortran
+  compilers:
+    -DPREPEND_FORTRAN -DNO_APPEND_FORTRAN -DUPPERCASE_FORTRAN
+    -DUNDERSCORE_G77
+
+  When using -DF2PY_REPORT_ATEXIT, a performance report of F2PY
+  interface is printed out at exit (platforms: Linux).
+
+  When using -DF2PY_REPORT_ON_ARRAY_COPY=<int>, a message is
+  sent 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.

+
+    There exists two usage cases where analyzing dimensions
+    specifications are important.
+
+    In the first case, the size of output arrays must be defined based
+    on the inputs to a Fortran function. Because Fortran supports
+    arbitrary bases for indexing, for instance, `arr(lower:upper)`,
+    f2py has to evaluate an expression `upper - lower + 1` where
+    `lower` and `upper` are arbitrary expressions of input parameters.
+    The evaluation is performed in C, so f2py has to translate Fortran
+    expressions to valid C expressions (an alternative approach is
+    that a developer specifies the corresponding C expressions in a
+    .pyf file).
+
+    In the second case, when user provides an input array with a given
+    size but some hidden parameters used in dimensions specifications
+    need to be determined based on the input array size. This is a
+    harder problem because f2py has to solve the inverse problem: find
+    a parameter `p` such that `upper(p) - lower(p) + 1` equals to the
+    size of input array. In the case when this equation cannot be
+    solved (e.g. because the input array size is wrong), raise an
+    error before calling the Fortran function (that otherwise would
+    likely crash Python process when the size of input arrays is
+    wrong). f2py currently supports this case only when the equation
