CompHEP-4.4.0. Release notes

//Copyright (C) 2003 CompHEP Collaboration//

**ATTENTION! The version 4.4.0 has some incompatibilities with previous one!**

===== Changes v.4.2.1 -> v.4.4.0 =====

==== Incompatibilities ====

New scheme of work with initial beams and final composite particles was changed.

If you have a private model and want to use them with CompHEP-4.4.0, you have to copy cpart1.mdl file to cpartN.mdl file where N is a number of your model by commands:

  cd path_to_user_working_directory/model
  cp cpart1.mdl cpartN.mdl

All new composite particles must be introduce into table by using edit model facilities.

==== Fix the bugs and clean up code. ====

  * Compilation bug when CERN libraries do not available
  * Make randomization of momenta of 2 last particles in event file.
  * QCD lambda are taken from PDF now.

==== Documentation and help files ====

  * SYMB_BATCH-HOWTO
  * NUM_BATCH-HOWTO
  * Help for beam table (s_beam_1.txt)
  * Help for structure function table (s_strfn_1.txt)

==== Interface ====

  * Symbolic part
    * Add table for initial beam (proton, anti-proton, …)
    * Introduce switch F3 from beams to particles and vs.
    * Change composite particle table (see [1])
    * Introduce switch F3 from composite particles to particles and vs.
    * Symbolic conservation law is off by default.
    * LOCK file is restored.
    * Maximum sum of output and input particles (MAXINOUT) is 10 by default.

  * Numerical part
    * re-arrange menu "Width scheme"
    * Change "Equiv.Photon(…)" to WWA

  * Common
    * Re-arrangement of usage of messages and warnings.

==== Source structure ====
  * All CompHEP libraries were collected into lib subdirectory
  * CompHEP PDF file standard description move to tbl-pdf directory
  * Files drandXX.[ch] move to service2 subdirectory

==== Miscellaneous ====
