5 # SYNOPSIS

7 # AX_PYTHON
8 #
9 # DESCRIPTION
10 #
11 # This macro does a complete Python development environment check.
12 #
13 # It recurses through several python versions (from 2.1 to 2.5 in this
14 # version), looking for an executable. When it finds an executable, it
15 # looks to find the header files and library.
16 #
17 # It sets PYTHON_BIN to the name of the python executable,
18 # PYTHON_INCLUDE_DIR to the directory holding the header files, and
19 # PYTHON_LIB to the name of the Python library.
20 #
21 # This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG),
22 # PYTHON_INCLUDE_DIR and PYTHON_LIB.
