+# - Find SWIG
+# This module finds an installed SWIG. It sets the following variables:
+# SWIG_FOUND - set to true if SWIG is found
+# SWIG_DIR - the directory where swig is installed
+# SWIG_EXECUTABLE - the path to the swig executable
+# SWIG_VERSION - the version number of the swig executable
+#
+# The minimum required version of SWIG can be specified using the
+# standard syntax, e.g. FIND_PACKAGE(SWIG 1.1)
+#
+# All information is collected from the SWIG_EXECUTABLE so the
+# version to be found can be changed from the command line by
+# means of setting SWIG_EXECUTABLE
+#
