- Keep sorted for human lookup. At runtime, a hash table is used.
- do **NOT** conditionally (#ifdef, #ifndef) define a function *NAME*:
doing so will cause user code that works against a --without-XYZ binary
to fail with name collisions against a --with-XYZ binary.
Use something similar to GEOM_BUILDER instead.
- keep 1 line per entry, it makes grep | sort easier
