  	Notes:

	(1) -- If this keyword appears before any GROUP keyword, it applies to
	       all groups binaries are assembled from by default.  If the
	       keyword appears after a given GROUP keyword, it applies to that
	       group only, and overrides any default which may earlier have
	       been established with the same keyword.

	(2) -- The hook program will be passed the subject line of the lowest-
	       numbered piece of the binary image on standard input.  It
	       cannot be invoked with arguments (yet).

 	(3) -- If the string "$h" appears unescaped in the command, it will be
	       replaced before the command is invoked with the "head" of
	       the filename of the binary.  Similarly, "$t" will be replaced
	       with the "tail", and "$f" will be replaced with the entire
	       filename.  The head and tail of "foo.gif" are "foo" and "gif",
	       respectively.

	(4) -- The SPOOL and NNTP keywords may not both appear in the same
	       configuration file.
