# This macro does a complete Python development environment check.
# It recurses through several python versions (from 2.1 to 2.6 in this
# version), looking for an executable. When it finds an executable, it
# looks to find the header files and library.
# It sets PYTHON_BIN to the name of the python executable,
# PYTHON_INCLUDE_DIR to the directory holding the header files, and
# PYTHON_LIB to the name of the Python library.
# This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG),
# PYTHON_INCLUDE_DIR and PYTHON_LIB.
