#MODULE check_occults

#***********************************************************************
"""

**PURPOSE** --
Check that the proper amount of time has been left command groups.

Developed from CHECK_OCCULTS.COM.

**DEVELOPER** --
Don Chance

**MODIFICATION HISTORY** --
Initial implementation 5/11/01
Raise an error when the RMS file does not exist. Also, append to an
already existing error file. dc 4/21/03
Added some major capabilities to check overlaps between a number of
PLCP groups. mdr 8/4/09
Don't ignore back-to-back commands that are the same. mdr 10/20/09
Refine slew regex. drc 11/02/09
Fix a bug checking for overlaps with PCPTERM and PTERMIN. mdr 11/16/09
Add the combined F1/F2 maintenance slew group and correct time. mdr 4/19/10
Mods for new maintenance slew timing. mdr 2/16/12
Correct issues in 1|2-gyro mode verses 3|T-gyro mode. mdr 8/27/15
