# This is a transition aid. It extracts old-style configuration information
# from a config file and writes an equivalent device.hints file to stdout.
# You can use that with loader(8) or statically compile it in with the
# 'hints' directive. See how GENERIC and GENERIC.hints fit together for
# a static example. You should use loader(8) if at all possible.
