+# SYNOPSIS
+#
+# SWIG_PYTHON([use-shadow-classes = {no, yes}])
+#
+# DESCRIPTION
+#
+# Checks for Python and provides the $(SWIG_PYTHON_CPPFLAGS), and
+# $(SWIG_PYTHON_OPT) output variables.
+#
+# $(SWIG_PYTHON_OPT) contains all necessary SWIG options to generate code
+# for Python. Shadow classes are enabled unless the value of the optional
+# first argument is exactly 'no'. If you need multi module support
+# (provided by the SWIG_MULTI_MODULE_SUPPORT macro) use
+# $(SWIG_PYTHON_LIBS) to link against the appropriate library. It contains
+# the SWIG Python runtime library that is needed by the type check system
+# for example.
