#MODULE notify_ncc_comcons
#
#***********************************************************************
"""

**PURPOSE** --
Sends NCC a mail message listing the COMCONs for a given SMS to hopefully
avoid having TDRS shortfalls over the time periods for COMCONs.

Based on NOTIFY_NCC_COMCONS.COM and COMCON_SMS_PARSE.FOR

**DEVELOPER** --
Gary Bower

**MODIFICATION HISTORY** --

o Initial implementation 12/21/01
o Include modifications from Python review - G. Bower 1/16/02
o Include more modifications from Python review. - G. Bower 2/11/02
- SMS version number is not required in input.
- Define the function sms_parse_comcon.
- Use calendar_util to parse the calendar display.
o Allow email distribution list APP 07/28/04
