acis-backstop.pl script documentation

1. Introduction:
   The acis-backstop.pl script extracts the ACIS commands and relevant information from the backstop file to create a file to review for the current spacecraft command load. The ACIS observing parameters are then compared against the ACIS observing parameters that are stored in the ObsCat. History files are used as input and output to create a continuity and to create a timeline of the spacecraft configuration for real-time webpages. After a load has been approved, ACE-update.pl must be run. This script concatenates the weekly history files produced by acis-backstop.pl to the global history files used in producing the ACIS real-time hardware telemetry web page as well as being used in deriving the ACIS orbital fluence based on ACE/EPAM data (see acis-fluence_P3pscaling.pl and acis-fluence_FP6pscaling.pl).
2. Execution depandancies:
   Requires the user to be on the HEAD LAN and is run via the lr script.
