TITLE: select_tut_windows.py
DEVELOPER: Alan Patterson, 24-Jul-2003

PURPOSE: The tool selects the TUT windows from the TUT file
specified given the TDRS, service and time window limits

USAGE: do select_tut_windows tutfile -tdrs=...,... -service=...,...
-start=
-end=
where -tdrs specifies a list of acceptable TDRS
(TDE,TDW,171,TDS)
-service specifies a list of acceptable
services (MAR,MAF,SSAF)
-start specifies the start time
-end specifies the end time
-outfile an output file may be specified, default
is to print to the screen
RETURNS: Nothing

MOD HISTORY:
Initial version app 07/24/03
