CompHEP-4.4.90. Release notes


**ATTENTION! THE VERSION 4.4.90 IS A TEST RELEASE! STILL NOT FOR SERIOUS PHYSICS RESEARCH!**

==== Incompatibilities. ====

  * A new format of the initial state in session.dat.
  * ComHEP has two regimes of compilation, with or without LHAPDF. CompHEP with LHAPDF has incompatible beam    strfun tables. So, these tables will be empty if a user tries to use old files in the new version. No problems in ComHEP without LHAPDf.
    

==== Fixed bugs. ====

  * Several bugs in generation of session.dat with s_comphep
  * Wrong values of some commands in tag of the event default file format.

==== Changes. ====

  * Symbolic part:
    * All PDFs in the beam/strfun tables have prefix PDF (or LHA, if LHAPDF is interfaced)
    * Proper generation of session.dat in s_comphep.
    * Lots of internal re-arrangements (to symplify the program structure).

  * Numerical part:
    * A new improved version of num_batch.pl
    * Diagram viewing is available in n_comphep (a new option in the main menu)
    * Re-arranged menu "Initial State". Beam particle and PDF are separated.
    * The LHA event file format has been added, still with no extra HepML tags. 

  * Common:
    * Now CompHEP is compatible with gcc-4.x
    * A new version of make_tab. Now it can processes files with several subprocesses.
    * CompHEP can be compiled in two different modes: with OR without LHAPDF.
    * Several options to ./configure have been added: --with-gcc4, --with-lhapdf, --debug, --help 

  * Documentation
    * New NUM_BATCH-HOWTO
    * LHAPDF_in_CompHEP-HOWTO

==== TODO ====
  * Mixing of several event files in LHAef.
  * Check LHAPDF-compatible session.dat in internal-PDF-compatible n_comphep (and vice versa)
  * Help files to the new "Initial state" menu
