[Rivet] Pythia6 419 built with autotools: 419.ac , 419.ac.2

[Alberto Ribon]

  Hello,

  as a first step toward the use of autotools for building
  GENSER packages, we have prepared the "autotoolized"
  version of the latest Pythia6 release, 419, available in:

  /afs/cern.ch/sw/lcg/external/MCGenerators/pythia6/419.ac/
                          ...                       419.ac.2/

  (the difference between the two is, as usual, only on
   the HEPEVT size: 4000 in 419.ac, 10000 in 419.ac.2)

  and tar-balls (source and libraries) are also available in:

  /afs/cern.ch/sw/lcg/external/MCGenerators/distribution/pythia6-419.ac*

  According to our tests, Pythia6 419 built with autotools
  behave the same as built with the traditional, current
  GENSER building mechanism
  (the latter has been released in GENSER few weeks ago 
   and is available in:
     /afs/cern.ch/sw/lcg/external/MCGenerators/pythia6/419/
                           ...                         419.2/
  ).
  
  Before adopting autotools in GENSER as the default building
  mechanism, it is important that users and experiments perform 
  extensive tests on this version of Pythia6, especially running 
  on the Grid. Particular attention should be paid in the case
  that the libraries are not taken from GENSER but built from
  source and used on the Grid.

  I would appreciate your feedback possibly before the 
  end of January 2009. Thanks!
 
  Best regards,
                Alberto
