Yeah, most people don't know how to use camera{} before reading the docs either.
The macros would come with documentation. I don't see the problem.
As for modifying it, you don't have to, but at least it's possible this way. Are
you saying if it was hard-coded you could dl the source and recompile it more
predictably than with modifying a macro?
