19 # AM_PATH_PYTHON([MINIMUM-VERSION])
21 # Adds support for distributing Python modules and packages. To
22 # install modules, copy them to $(pythondir), using the python_PYTHON
23 # automake variable. To install a package with the same name as the
24 # automake package, install to $(pkgpythondir), or use the
25 # pkgpython_PYTHON automake variable.
27 # The variables $(pyexecdir) and $(pkgpyexecdir) are provided as
28 # locations to install python extension modules (shared libraries).
29 # Another macro is required to find the appropriate flags to compile
32 # If your package is configured with a different prefix to python,
33 # users will have to add the install directory to the PYTHONPATH
34 # environment variable, or create a .pth file (see the python
35 # documentation for details).
37 # If the MINIUMUM-VERSION argument is passed, AM_PATH_PYTHON will
38 # cause an error if the version of python installed on the system
39 # doesn't meet the requirement. MINIMUM-VERSION should consist of
40 # numbers and dots only.
