Ok, good.

Some background information about what I am experimenting. To make the 
ECSS standard happy, we have to deliver a Software Configuration File 
(SCF) for example. This overlaps a bit with the information necessary to 
build RTEMS. I would like to concentrate the information in Doorstop 
maintained files and generate different outputs based on the intended 
usage, e.g. an SCF or build files (Makefile, waf). Another example is 
that we may have a requirement like this: The compiler flags for the XYZ 
BSP shall be "-O2 -g -mleon3". We could add the compiler flags to a 
BSP-specific configuration item which has a "cflags: -O2 -g -mleon3" 
attribute. We can use this attribute to generate a human readable 
requirement in an Software Requirements Specification (SRS) and the 
build file. The compiler flags just have one master data, everything 
else is derived and produced by tools.
