+-- Special routines exist for the enumeration types in these packages.
+
+-- Note: this is an obsolete package, replaced by System.Img_Enum_New, which
+-- provides procedures instead of functions for these enumeration image calls.
+-- The reason we maintain this package is that when bootstrapping with old
+-- compilers, the old compiler will search for this unit, expectinng to find
+-- these functions. The new commpiler will search for procedures in the new
+-- version of the unit.
