+These files were in the Waste 1.3 distribution, but they are missing from the
+Waste 2.0 distribution. At least: from the 2.0 distribution as included with
+MetroWerks CodeWarrior. As the Python Waste module needs them I have included them
+here. There were a few minor changes (in function signatures) to accomodate
+slight changes in the Waste 2.0 headers.
+
+All the copyright notices in the files and in Waste 1.3 seem to indicate that it
+is fine to redistribute these files. If I am mistaken in this please let me know
