That's just a mechanism to generate delegation. And you redefine methods a=

Those are not really needed. And if you want to have them then I'd make th=
em either contain a default implementation if there exists one or throw an =
exception which explains that this method must be implemented for the class=
.
True, but I want to document the API somewhere central. I raise exceptions =
saying the method must be implement.

You are hiding specific state in a constant. I don't like that because it =
will prevent accessing multiple different source control systems in the sam=
e program or from multiple threads. I find that requirement to be able to =
invoke all the methods through the constant leads to a situation where you =
severely cripple modularity and reusability without really gaining somethin=
g.
Also true, if I wanted to do that, but I don't. I just need to initialise i=
t at startup and use the source control system that was automatically deter=
mined from then on, without knowing which one it is. I think this API is wo=
rking really well for me... I also just like the API of SourceControl.check=
out etc.
Kind regards
robert
