    Eurodec is a general purpose Monte Carlo program for the
    fragmentation and decay of quarks, di-quarks, heavy leptons etc.
    It can be attached to the event generators:

       EUROJET - EUROPPB, Event generator for pp(bar) interactions,
               - EUREPEM, Event generator for e+e- interactions,
               - EUROEP,  Event generator for e-p interactions,
               - Your own event generator.

    The routine FRAGMT provides the steering of this program. The I/0
    follows through the common blocks /MOMGEN/ (input) and /RESULT/
    (input/output). 'NTEIL' is the number of particles already
    entered into /RESULT/ (the user should initialize 'NTEIL' !). New
    particles will be added starting from position 'NTEIL+1'. The
    arguments of the steering routine 'FRAGMT' the user has to
    provide (only when it is used as a stand-alone program) read:

    IP1    = pointer to first particle in the common /MOMGEN/,
    IP2    = pointer to last particle in the common /MOMGEN/ to be
             treated for fragmentation,
    NTEIL0 = particles from position NTEIL0+1 onwards will be used in
             the energy/momentum conservation procedure. Except for
             the treatement of the underlying event in hadronic
             interactions, NTEIL0 will generally be equal to NTEIL.

    The other commons are needed for control and/or
    initialization parameters (See Subroutine EUDCIN!).
    Before the first call to the steering routine is made the user
    should have made a call to the initialization package (EUDINI).
