When an application starts up, after it has performed it's needed startup,
it should make the Tool Locator call "MessageCenter" ($1501, page 24-14 of
the IIGS Toolbox Reference Manual, Volume 2), with an action code of $0002,
getMessage, and a MessType of $0001, file info type.  If you don't get
a "messNotFoundErr" ($0111), then the content of the MessData field will
be of the folowing structure:

MessData	block	0 = open the following files
			1 = print the following files
		str	'name1'
		str	'full pathname 2'
		...
		BYTE	0

The toolbox manual says that only MessType 1 has been defined, but
others may have been defined since it's publication.  Matt or Dave,
what's the scoop?
