958
# Adds support for distributing Python modules and packages. To
959
# install modules, copy them to $(pythondir), using the python_PYTHON
960
# automake variable. To install a package with the same name as the
961
# automake package, install to $(pkgpythondir), or use the
962
# pkgpython_PYTHON automake variable.
964
# The variables $(pyexecdir) and $(pkgpyexecdir) are provided as
965
# locations to install python extension modules (shared libraries).
966
# Another macro is required to find the appropriate flags to compile
969
# If your package is configured with a different prefix to python,
970
# users will have to add the install directory to the PYTHONPATH
971
# environment variable, or create a .pth file (see the python
972
# documentation for details).
974
# If the MINIMUM-VERSION argument is passed, AM_PATH_PYTHON will
975
# cause an error if the version of python installed on the system
976
# doesn't meet the requirement. MINIMUM-VERSION should consist of
977
# numbers and dots only.
