/* 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.
