# This file contains the table of known operating system names.
#
# Architecture names are formed as a combination of the system name
# (from this table) and CPU name (from cputable) after mapping from
# the Debian triplet (from triplettable).
#
# Column 1 is the Debian name for the system, used to form the system part
# in the Debian triplet.
# Column 2 is the GNU name for the system, used to output build and host
# targets in ‘dpkg-architecture’.
# Column 3 is an extended regular expression used to match against the
# system part of the output of the GNU config.guess script.
#
# <Debian name>		<GNU name>		<config.guess regex>
