4.5. What the heck is a +IN suffix on a file?

	On the UNIX PC, "+IN" denotes an "Installable File".  If you
were to use the UA it would show that it's an Installable File.  The
Installable format is just a normal cpio archive.  The file can be
installed by hand by doing:

		# mkdir /tmp/install
		# mv FILE+IN /tmp
		# cd /tmp/install
		# cpio -icduvmB < ../FILE+IN
		[...]
		# ./Install

	A list of other Suffixes appears in the file
/usr/lib/ua/Suffixes.
