# Replacement for /usr/bin/nl in the sgs/messages piglatin tests.
#
# usage: sgsmsg_piglatin_nl start_index
#
# where start_index is the staring number
#
#
# The sgs/messages test target used to use /usr/bin/nl as part
# of the process of adding a piglatin translation to the file.
# The invocations looked like:
#
# nl -v1 -i2
# or
# nl -v2 -i2
#
# This adds line numbers to the beginning of each non-empty line
# from stdin, counting by 2, and starting at either 1 or 2, depending
# on whether the master file, or the piglatin file is being processed.
#
# The output format is "%6d\t%s". Empty lines are replaced with
# 7 space characters in the output, and the line number is not
# incremented.
#
# The problem with nl is that it has a 2K buffer for input lines,
# and our catalog files can have some very long lines, thanks to
# the elfedit module help strings. This perl script emulates nl
# to the extent required to replace it in the sgs piglatin tests,
# while not breaking lines longer than 2K characters.
