xkb-olpc

[Yioryos Asprobounitis]

I'm trying to find out where/how the /usr/share/X11/xkb/compat/olpc and /usr/share/X11/xkb/symbols/olpc files are generated.
I could not find them in olpc-git or Xorg X11R7.5 sources. Or in configuration files I looked at? 
Where are they coming from?
Are they part of the xserver/XkeyboardConf configuration?
Are they generated by a specific script/option? which/what?
Where could I find the xserver configuration script/parameters for the XO-1/F11 builds?
Thx
