+ * NAME
+ * file type.c - implementation of the datastructure to hold
+ * type information.
+ * COPYRIGHT
+ * (C) 2001 by Universitaet Karlsruhe
+ * AUTHORS
+ * Martin Trapp, Christian Schaefer, Goetz Lindenmaier
+ *
+ * NOTES
+ * This module supplies a datastructure to represent all types
+ * known in the compiled program. This includes types specified
+ * in the program as well as types defined by the language. In the
+ * view of the intermediate representation there is no difference
+ * between these types.
+ *
+ * There exist several kinds of types, arranged by the structure of
+ * the type. A type is described by a set of attributes. Some of
+ * these attributes are common to all types, others depend on the
+ * kind of the type.
+ *
+ * Types are different from the modes defined in irmode: Types are
+ * on the level of the programming language, modes at the level of
+ * the target processor.
+ *
+ * SEE ALSO
