I'm  guessing Andrzej meant by default. Also, isn't CinePaint dead upstream?

I don't see ArgyllCMS as a CMS. It's an excellent tool we can use to
generate profiles, but it's not a component that we can, for example,
say "give me all the profiles installed on the system". But that comes
down to how you define a CMS. The ultimate example is lcms, which is
an excellent library for converting pixels and reading data from ICC
profiles, but again doesn't satisfy my definition of a CMS.

Maybe it's me that's wrong in my definition. I should perhaps start
calling colord a "Color Management Framework" as CMS as a term seems
so horribly overloaded.

In colord, DBus is used as the transport. In Ghostscript we're
registering profiles from the PPD with colord. GCM is getting the
default monitor profile from colord and setting the _ICC_PROFILE
atoms. The fact that I'm using DBus rather than a socket is just a
trivial implementation detail.
