In the following we describe and motivate a project dealing with the rewriting of Dlprotein (a Parallel Molecular Dynamics
Package recently developed by the authors) into a more flexible tool using Object oriented technology. The motivation of this
project is based on the assumption that Object Oriented paradigm can improve the code in terms of portability, maintenance
and further developments. We present here briefly the package and discuss the first changes according to Object Oriented Paradigm
we introduced.
