      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 2.6 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.
