30# Replacement for /usr/bin/nl in the sgs/messages piglatin tests.
31#
32#	usage: sgsmsg_piglatin_nl start_index
33#
34#	where start_index is the staring number
35#
36#
37# The sgs/messages test target used to use /usr/bin/nl as part
38# of the process of adding a piglatin translation to the file.
39# The invocations looked like:
40#
41#	nl -v1 -i2
42# or
43#	nl -v2 -i2
44#
45# This adds line numbers to the beginning of each non-empty line
46# from stdin, counting by 2, and starting at either 1 or 2, depending
47# on whether the master file, or the piglatin file is being processed.
48#
49# The output format is "%6d\t%s". Empty lines are replaced with
50# 7 space characters in the output, and the line number is not
51# incremented.
52#
53# The problem with nl is that it has a 2K buffer for input lines,
54# and our catalog files can have some very long lines, thanks to
55# the elfedit module help strings. This perl script emulates nl
56# to the extent required to replace it in the sgs piglatin tests,
57# while not breaking lines longer than 2K characters.
