Property inheritance in a property file

[Roman Rytov <ro...@tti-telecom.com>]

In a property file I define a property X, let's say X=x,. Then I need to
define Y and Z base on the next logic: Y=x/y and Z=x/z, or in other words:
Y=${X}/y and Z=${X}/z. 

I know how to do it in a build descriptor but Is there a way to do it in a
property file?
