updating TWIST GEANT 

May 6th 2001 - Specific to GEANT version 1.4

If you already have extracted GEANT from CVS in the past
you only need to do an update. 

You have a choice of updating  the version you already
have or making a new directory tree (recommended)

Make a new directory tree. !! Recommended !!
-------------------------
Step 1 - 
> cd $GEANT_COMMANDS 
> pwd (check where you are, this should be a subdirectory named geant)
       example: /home/renee/work/geant
------
Step 2 - 
Decide if you want to use the STABLE version 1.4 or if 
you wish to get/participate easily in all new development.

STABLE version 
> cvs checkout -P -d 1.4 -r v1-4  geant 
     (this should create a directory tree called 1.4)
> setup geant 1.4
or 
Development version
> cvs checkout -P -d 1.4devel   geant 
> setup geant 1.4devel

In your .login, where you had the command "setup geant 1.3" 
changed it to the appropriate version name "setup geant 1.4"
or "setup geant 1.4devel"

-------
Step 3 - 
> cd $GEANT_ROOT  (this should put you in your directory
                    .../geant/1.4)
> ./make_all      (this scripts rebuilds everything)
 
- Sources are in $GEANT_SOURCE
  Run files are in $GEANT_RUN
  Look at files e614.com and e614.ffcards which have changed 
  significantly since version 1.3

----------------------------------------------------------------

Updating the version you already have
-------------------------------------
!!! BEWARE; this method will overwrite several files which 
    you might already have modified. 

>setup geant 1.3
>cd $GEANT_ROOT
>cvs update 
>./make_all

Note that your top directory will still be called 1.3 
and you will still need to issue "setup geant 1.3" although
you will be working with geant 1.4
