    1717For those reactions, the flow of particles is modelled within a [wiki:physicsInput Boltzmann-Uehling-Uhlenbeck (BUU) framework].
    18 The relevant degrees of freedom are '''mesons''' and '''baryons''', which propagate in mean fields and scatter according to cross sections which are tuned to the energy range of 10 MeV to more than 10 GeV. In the higher energy regimes the concept of '''pre-hadronic''' interactions is implemented in order to realize ''color transparancy'' and ''formation time'' effects.

    20 The new numerical implementation, named '''GiBUU''' (aka ''The Giessen BUU Project''), is written in modular [wiki:programmingLiterature Fortran 2003] and based upon a [http://subversion.tigris.org/ Subversion] version control system, which allows for a concise control over the full development phase of the code.

    2226The [wiki:GiBUU_Code_history history of the code] is rather long and reports about several main development steps. The present initiative accomplished a total rewrite of the source code in a present-day computing language. The main goals of this effort were ''modularization'' to allow for a more transparent multi-user development process, a strict ''reduction of global variables'' for a more transparent debugging procedure, an ''improved control over the development phase'' such that modifications can be backtracked and a ''unified standard version''.
