#
# SYNOPSIS
#
-# AX_PYTHON_DEVEL([version])
+# AX_PYTHON_DEVEL([version[,optional]])
#
# DESCRIPTION
#
# version number. Don't use "PYTHON_VERSION" for this: that environment
# variable is declared as precious and thus reserved for the end-user.
#
+# By default this will fail if it does not detect a development version of
+# python. If you want it to continue, set optional to true, like
+# AX_PYTHON_DEVEL([], [true]). The ax_python_devel_found variable will be
+# "no" if it fails.
+#
# This macro should work for all versions of Python >= 2.1.0. As an end
# user, you can disable the check for the python version by setting the
# PYTHON_NOVERSIONCHECK environment variable to something else than the
# modified version of the Autoconf Macro, you may extend this special
# exception to the GPL to apply to your modified version as well.

Moreover, to disable this check, set PYTHON_NOVERSIONCHECK
