+// = DESCRIPTION
+//    This file contains examples of IDL code that has 
+//    caused problems in the past for the TAO IDL
+//    compiler. This test is to make sure the problems
+//    stay fixed.

+
+// This file, along with its companion full.idl, test the
+// handling of forward interface declarations that are
+// not defined in the same IDL file. The two files have
+// mutually dependent interfaces. It is no longer necessary
+// for such ILD files to include each other, as long as 
+// they are part of the same build.
