81	# batch_scp has up to 5 arguments (first 4 are mandatory):
82	# $1 = IP-addres of remote (target) machine
83	# $2 = file to be transferred
84	# $3 = directory of remote machine, where file should be copied to
85	# $4 = filename that file should be given on remote machine
86	# $5 = file extension (optional argument)
87	#
88	# ATTENTION: problems might occur if directories on remote machine include very
89	# old files for which "ls -al" does give "year" as modification
90	# time instead of "hh:mm". In such a case, batch_scp cannot check the
91	# filename and may not find the file (e.g. if option -g is used).
