tooling/help for rewriting C projects with betterC

[yawniek]

is there any tooling or tutorials on how one would approach a 
(partial) rewrite for bigger C projects that use e.g. cmake ?

is there a way parts of it could be automated (if so which parts) 
?

this might help D a lot if people that want to learn/rewrite a 
library would get support and appropriate tooling.
also best practices and help on how C patterns can be transformed 
to (safe!) d code.
