# Command:
#   mbm_copy

#   a datalist, using the MB-System file suffix convention
#   to name the output files.
#
# Basic Usage:
#   mbm_copy -Foutputformat -Idatalist [-H -V -C -T]

# This version of Getopts has been augmented to support multiple
# calls to the same option. If an arg in argumentative is followed
# by "+" rather than ":",  then the corresponding scalar will
# be concatenated rather than overwritten by multiple calls to
# the same arg.
#
# Usage:
#      do Getopts('a:b+c'); # -a takes arg, -b concatenates args,
#			    # -c does not take arg. Sets opt_* as a
#                           # side effect.
