+/* gegl-chant contains incantations to that produce the boilerplate
+ * needed to write GEGL operation plug-ins. It abstracts away inheritance
+ * by giving a limited amount of base classes, and reduced creation of
+ * a properties struct and registration of properties for that structure to
+ * a minimum amount of code through use of the C preprocessor. You should
+ * look at the operations implemented using chanting (they #include this file)
+ * to see how it is used in practice.
