-# 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.
