What I mean is: if the first user of a controller does things properly
(create startup and interface unit, extend t_embedded.pas), subsequent
users of the same controller have much less work, they need only to pass
the correct parameter to the compiler and not to fiddle with
configuration files, directives etc. The compiler takes care of everything.
