=> I don't understand what exactly is the semantics of the `abs' value.
=> Does it means that I have to specify an absolout system path, i.e. one
=> that starts with `/' under UNIX, 

Yes, a UNIX path. Either starting from /, or relative to the current directory
(at the time the file is loaded => a rather impredictable value).

=> or can I also give a  path that is
=> relative to the rdb file that specifies the Root property? 

No, you cannot. And nothing in the documentation suggests that this feature is
available. Due to technical reasons (use of X software today, and Intrinsics
compliance in the future) I think that this cannot be supported.

Maybe you can use cpp to configure your resource files, setting location
resources according to the directory where your software is to be installed.

Also, the #include directive will be allowed in resource files to have other
resource files loaded as soon as Centaur is compiled using X11R5 libraries.
