# shellwords.rb: Manipulates strings a la UNIX Bourne shell
#

#
# This module manipulates strings according to the word parsing rules
# of the UNIX Bourne shell.
#
# The shellwords() function was originally a port of shellwords.pl,
# but modified to conform to POSIX / SUSv3 (IEEE Std 1003.1-2001).
