+# SYNOPSIS
+#
+#   AX_PYTHON_MODULE(modname[, fatal, python])
+#
+# DESCRIPTION
+#
+#   Checks for Python module.
+#
+#   If fatal is non-empty then absence of a module will trigger an error.
+#   The third parameter can either be "python" for Python 2 or "python3" for
+#   Python 3; defaults to Python 3.
