# Define a rule to create the map files from downloaded text input
# files using a script.  Arguments:
#
# 1: encoding name used in output files (lower case)
# 2: script name
# 3: input text files
# 4: argument to pass to script (optional)
#
# We also collect all the input and output files in variables to
# define the build and clean rules below.
#
# Note that while each script call produces two output files, to be
# parallel-make safe we need to split this into two rules.  (See for
# example gram.y for more explanation.)
