USAGE:
   cp-from-sg [options] { month | prev } [day-expression [day-expression ...]]

PURPOSE:
Copies GWR UIPC collected data from machine Brimer to Tidedata and Tidearchive.
This program is installed on machine utter under /home/scg/bin

In the most simple form,
   cp-from-sg -X prev
the command copies all data types of the previous month from 
RAW_o054  DAY_o054  and  MON_o054 
on machine brimer, bzip2's the RAW files, and copies the bunch to the archive. The scope of the RAW data is extended to the
first day of the current month. Therefore, this script should be run in this form not before the second day of a month.

For a specific month, month  must be given as  01...12. Extension of RAW to the first day of the following month
will be attempted.

In the version with specified day-expressions, the scope is limited to RAW files.

If days are not specified, only new files are scp'ed - unless option -F is used.
