# NAME:
#	rsync_ssw
# PURPOSE:
#	Python cgi script to synchronize master SMEI tree with the SSW mirror 
# CALLING SEQUENCE:
#	rsync_ssw.py
# OPTIONAL INPUT PARAMETERS:
#	-nodoc		if set, no new documentation is generated
# PROCEDURE:
#	List of subdirectories in $SMEI to be mirrored is hardcoded
#	Uses rsync
# CALLS:
#	tiny.is_there
# MODIFICATION HISTORY:
#	JAN-2002, Paul Hick (UCSD/CASS)
#	FEB-2002, Paul Hick (UCSD/CASS)
#		Removed $SMEI/pro from SSW_SMEI master
#	AUG-2002, Paul Hick (UCSD/CASS)
#		Output file is now created in subdirectory ssw_mirror
#		of the directory where this script is located.
#		Added call to 'idl run_ssw_smei.pro' to update the html
#		documentation before calling rsync.
#	JAN-2003, Paul Hick (UCSD/CASS)
#		Added -nodoc keyword
