+ * cppmagic - Abuse of the C preprocessor
+ *
+ * This contains a bunch of fancy macro techniques such as
+ * preprocessor-time evaluated conditionals and (quasi) recursion and
+ * iteration.
+ *
+ * It's based on these articles:
+ *  - http://jhnet.co.uk/articles/cpp_magic
+ *  - https://github.com/pfultz2/Cloak/wiki/C-Preprocessor-tricks,-tips,-and-idioms
+ * and code from the Boost C++ library.
