New Version 2.3 of ESPACE - May 19, 1997

  The new version 2.3 of ESPACE is available on /work/halla/software/
  and on the web, http://www.cebaf.gov/Hall-A/data_reduc/calibrations/
  quick_install.html.

  You will also need the new database (see note 6 below).  A useful
  new subdirectory in the distribution is /r2-3/util_notsource (it
  contains sfmakedepend, this README, an example kumac file and an
  example database db_coin_1.)


    Changes between 2.2.4  and  2.3 
    ================================

  1. New Makefile and sfmakedepend. (Jeff Templon, 3/31)
     sfmakedepend is available at ~rom/bin, and also on www.

  2. Linux compatibility modifications from Jeff (3/31).
     The obviuosly safe ones were installed; the less safe ones 
     were left in the new /linux directory (see README there).  
     In a future patch the Makefile will allow easy Linux compilation.

  3. FPP code  (Ed Brash, et.al., 4/26)
  
  4. First version of Aerogel code.  (Ed Brash, 4/26)

  5. Treatment of helicity information.  (EJB, 4/26)
     BCM and helicity merged in scaler_update, which needs to
     be rewritten (see notes in scaler_update)   (RWM)

  4. Repairs to tracking and beam_vertex (Juncai Gao, 5/14)
     Big improvment in Ytarget, works for O16 experiment but 
     beam_vertex needs to be rewritten for cryotarget.

  5. Improvements to coincidence time-of-flight. (Nilanga, 5/14)

  6. New DATABASE which contains optics (it is tied to new
     tracking, so don't mix old database with new code, etc).
     Database also contains Aerogel and Leadglass constants.

  7. First version of Lead-glass code.  (Surik Mehrabyan, 5/15).
     Calibration and cluster-finding algorithms, some particle ID.
     If you don't have calibration file, it uses default
     constants.  Some documentation is promised soon.
