/* A collection of stuff heavily dependent on the configuration info
* in config.h. The idea is that configuration-dependent tables should
* be located here to avoid having to pepper lots of .c files with #ifdefs,
* requiring them to include config.h and be recompiled each time config.h
* is modified.
