Tim, thanks for hint with ant. I was trying to implement generation with
using ant tasks(it seemed to me more elegant solution, than to work with
file streams in Java code) and found that ant can't work with cycles. I can
run replace task for certain file name and can't do this with parametrized
file names for a set of modules:( There is an extension of ant called
"Ant-Contrib" [2] where cycles are implemented. Do you know if it can be
used in Harmony? Or may be there is a possibility to do replace task for a
set of modules just in pure Ant?
