Yes, it's generated entirely based on data provided in original source file.

More-or-less. The key difference is you will most likely look at the
generated file *once* to copy-and-paste the relevant macros to paste into
your source file for use (e.g. the relevant MethodDef stuff). But it's a
one-time thing that never has to be done again as long as you don't rename
a function or method.
