This is from the DOpusPLUS-CD. I assume it is ok to upload as Magellan II is 
now open-source.
This version matches DOpus Magellan II v 5.82, as opposed to the SDK on the 
OpusMagellanII.iso that is dated 1996. 


                        Directory Opus Magellan II

                       Software Development Kit 1.1

                   (c) 1998 Jonathan Potter & GPSoftware

-----------------------------------------------------------------------------

The Opus SDK kit allows you to access the functions in the dopus5.library,
and create your own modules, applications or other programs that use the
power of Directory Opus.

The contents of the SDK is as follows :

	docs	- Documentation for the dopus5.library
	include	- Include files
	lib	- Linker files
	example	- Example source code
	source	- Source to the modinit.o module

The include and linker files are all designed for use with a C compiler
(the example source code is set up to compile under SAS/C).

The examples that have been included are :

	module	- A basic module that adds one command to Opus and
                          opens a requester. Shows a simple example of
                          creating an Opus module.

	envoymodule	- A module that lets you set network information for
	                  files with Envoy. Shows an example of a simple
	                  user interface, using the Opus callback function
	                  and using a progress indicator.

	iconclock	- The source to the icon clock module. Shows how to
	                  write a module that is called on startup and remains
	                  resident. Also has an example of the new AppIcon
	                  features of Opus.

	viewfont	- The source to the ViewFont program. Shows how to
	                  create a more complex, resizeable user interface,
	                  and how to access menus.


See the C tutorial in the Tutorials directory on the DOpus PLUS CD for
