The Input is performed in the subroutine GUKINE. Two modes exist: the user can read 4-vectors from a file via the routine LCREAD in a format agreed for the workshop. Alternatively a routine USKINE is called, where users can implement their own event generators. At the moment an example for a simple single particle generator, an example for using PYTHIA, and an example for running background files is included.
The kine file is read in under the ``generic'' name kinfile, which again the user is expected to set.
Simulated events are passed to the reconstruction program or written to file. The format of the intermediate hit storage is explained later in this document.
Reconstructed events are written to file using a format developed and described in the context of the SIMDET fast simulation program. The exact file format and the definition of the different quantities saved are given later in this document.
