+# Each package is responsible for reporting which valid configurations

+# a failure to support a valid configuration from a meaningless
+# configuration.

+# machine specification into a single specification in the form:
+# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# it is wrong to echo any other type of specification
+
+# First pass through any local machine types.
