It is not that by intention that want to work around the design.
There are just few inconsistency I've encountered. Perhaps my knowledge
not deep enough.
gsl project.xml - it works from any folder (e.g. gsl
~/zstuff/malamute/project.xml)
gsl mlm_proto.xml - it works fine from src folder, but it fails from
different folder
The same program, but two different behaviors. What is the usage rule
for gsl?
