-c in Core is for the release, I left it that way for consistency between Core and dCore although I see your point. Same with the -l, I wanted to leave it the same.
I try to leave the utilities as close to behaving the same as I can so one does not have to use -c for release in Core, and -r in dCore for the same output. And that allows utilities that use things like version to be alble to more easily just work when ported to dCore.
