5 # SYNOPSIS

7 # AX_PYTHON
8 #
9 # DESCRIPTION
10 #
11 # This macro does a complete Python development environment check.
12 #
13 # It checks for all known versions. When it finds an executable, it looks
14 # to find the header files and library.
15 #
16 # It sets PYTHON_BIN to the name of the python executable,
17 # PYTHON_INCLUDE_DIR to the directory holding the header files, and
18 # PYTHON_LIB to the name of the Python library.
19 #
20 # This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG),
21 # PYTHON_INCLUDE_DIR and PYTHON_LIB.
