1) The top-level driver is ep_run.csh.
   Here's how you can run the code:

   ibmcl1> csh -c "./ep_run.csh 20010704 3 ibmcl1 0"

   1st Argument:   Date  
   2nd:            Spacecraft
   3rd:            Machine name
   4th:            0  <--- This is specific to the GCDC
   4th:            1  <--- This is for non-GCDC users

2) For non-GCDC users, you must edit the ep_control.csh
   file in order to specify multiple dates/times.

3) To set up required paths and environment variables for
   your own local machines, use ep_mpecl_paths.csh as
   a template, and tailor it to your needs.  You must
   name it appropriately, e.g. ep_mymachine_paths.csh and
   then the 3rd argument for ep_run.csh must be
   mymachine.

4) The history of updates is in the file snapshot_history
