# Name:         nsarch
#
# Description:  this file determines the system name and outputs the
#               platform information in a format used by Netscape build
#               scripts and utilities; this file is based on the GNU
#               "config.guess" utility; the GNU copyleft is provided
#               somewhere below...
#
#    For each platform supported by Netscape, we need to provide the
#    following definitions:
#
# Variable           Description
# --------           -----------
# NS_NAME:        one word, all upper case system name usually from uname -s that
#                 can be used for Makefiles and #defines
#
# NS_RELEASE:     release number of the OS; if there's a trademark name (like UnixWare),
#                 then this is typically the release number of the marketing name
#                 (like UnixWare 2.1) rather than the version of generic Unix it is
#                 based on (like System V r4.2)
#                 this number comes generally from uname -r, but on some systems
#                 we need to use uname -v
#
# NS_PRETTY_NAME: one word, mixed case system name similar to NS_NAME, but useful
#                 for scripts that output something for users to see

#
# This script attempts to guess a canonical system name similar to
# config.sub.  If it succeeds, it prints the system name on stdout, and
# exits with 0.  Otherwise, it exits with 1.
#
# The plan is that this can be called by configure scripts if you
# don't specify an explicit system type (host/target name).
#
# Only a few systems have been added to this list; please add others
# (but try to keep the structure clean).
