Installing display profiles/interfacing with gcm

[Florian Höch <lists+gnome-color-manager hoech org>]

Hi,

I'm currently looking for a way to install display profiles in a similar 
way as Argyll's dispwin does. So, I'm either looking for an utility 
'gcm-install-display-profile' <displayno> <filename.icc> that would copy 
the file, do the mapping displayno->device and write the neccessary info 
to device-profiles.conf (does gcm-install-systemwide do this?). Or for 
another way to achieve what I just described (DBus?). Reason I'm asking 
is I'd like to offer profile installation in a GCM-compatible way in 
dispcalGUI if GCM is also installed, as I'm currently only supporting 
the Argyll dispwin (UCMM) way.
Or is it safe/recommended to write to device-profiles.conf directly?
Then, I'd just have to figure out how to do the Argyll displayno -> GCM 
device mapping (btw, what's the $(ascii) in 
xrandr_$(vendor)_$(name)_$(ascii)_$(serial) mentioned in the GCM wiki?). 
Pointers welcome :)

Thanks in advance and regards
