[bug#68337] [PATCH 0/2] Add ajam and argyllcms

[striness]

From: Ulf Herrman <striness@tilde.club>

This patch series adds ajam, a variant of the Jam build tool pre-patched for
use with Argyllcms, and then adds Argyllcms, a Color Management System capable
of creating color profiles for scanners, cameras, displays, and printers.

I've verified that at least targen seems to work.

I wasn't sure where to put argyllcms, so for now I put it in (gnu packages
ghostscript) because that's where lcms is.

Note that there was some discussion surrounding Jam's license earlier.  I
don't believe that has concluded yet, but it seems likely that it will end up
classified as Free.

Ulf Herrman (2):
  gnu: Add ajam.
  gnu: Add argyllcms.
