+            configure/setup.py, or another automatic building system
+            and requires a specific swig version, let say 1.3.22 
+	    you can use:
+
+	       SWIG_FEATURES="-fakeversion 1.3.22"
+
+	     or
+ 
+               swig -fakeversion 1.3.22
+
+             and then swig -version will report 1.3.22 instead of the
+             current version.
+
