"""Examines the specified TDRS LIS file for cases where the H04 forward
services extend outside the MAR service for the event

TITLE: tdrs_lis_check.py
DEVELOPER: Alan Patterson, 30-Sep-2002

PURPOSE: The tool will examine the specified TDRS LIS file for cases
where the H04 forward service extends beyond the MAR service
for the event

USAGE: do tdrs_lis_check

where: is filename of the TDRS LIS file to be
examined

RETURNS: Nothing

MOD HISTORY:
Check for events without an MAR service. drc 12/2/02
Use tdrs_util utility app 02/25/03
Allow (coho) H04 to start early (30 sec) app 03/10/10
