I have a program in which I'd like to implement services.  That is, I'd  
like it available as a service to other programs.  As per the Appkit  
documentation in the release notes (2.0) I created a file that looks like  
this: (called services.txt)

--
Message: servicesMessage
Port: DATer 
Menu Item: Create DAT Contents
Send Type: NeXT filename pasteboard type
--
(above taken more or less from CopyPath.services)

and added the following line to my Makefile.preamble:
--
LDFLAGS = -sectcreate __ICON __services services.txt
--

This brings me to two questions:

	1.  Where is a list of the valid send types?  I don't really have
	write a program that asks the pasteboard for those strings, do I?

	2.  Why doesn't my program show up in the Services menu?  I tried
	rebooting with the program in LocalApps, and it doesn't show up in
	the workspace like the services for CopyPath do.

Note that I haven't implemented my Listner and servicesMessage method in  
my delegate yet.  I assume that his shouldn't prevent the service from at  
least showing up, right?  

I'd greatly appreciate ANY help.  Thanks in advance.
