Version	v4r1 (06 june 2002)
Description	Allows to write a complete decay selection in C++, is based on the complete new Event model (Particle & Vertex, MCParticle, MCVertex & ParticleID). Interfaces and at least one concrete implementation OO basic tools for physics analysis on real data are available. An example of offline physics selection for B->J/Psi(mu+mu-)Ks(pi+pi-) is provided in the PhysSelections package. It makes use of a DVAlgorithm base class to facilitate retrieval of Tools. Such selection is suggested to be used to guide people intending to write offline selection algorithms in using the basic tools. Some utility tools and tools to look at the MC truth are also available. Supports running of existing Fortran physics analysis and interfaces with the axsel package although WARNING is given that this will be dropped in the next version. Supports reading Zebra DST files produced with Brunel v5 or higher (the correct dbase for the files must be specified). WARNING is given that this will be dropped as soon as OO-DST test samples of decay channels will be available. RAWH files can also be read (SICBMC v245 or higher) but if more then minimal reconstruction is required it is recommended to use Brunel instead
