IAC ReadDted Project
--------------------

This directory ( iac_proj/rd_dted/ ) contains all the V code, source code,
HTML documentation, and installation information for the IAC project
"ReadDted".

The directory should be placed into your existing project directory, which
should already contain the IAC Project File structure, i.e., the iac_proj/,
iac_lib/ and v/ directories.

The file INSTALL contains information on how to edit the existing IAC
files: a single line addition to the iac_proj/iac_proj.v file, to add the
new ReadDted project, and additions to two of the files in the iac_lib/
directory, to link appropriate objects to the top-level IAC library page.

Once the files have been correctly installed, the low-level module of the new
project may be compiled. If you opt to leave the process unspecified, it will
by default use the "express" process. Doing so means the module may be
compiled by using one of the following commands in the top-level directory of
your project (whilst AVS/Express is not running):

	base -comp_proc express -exit
or
	make -f express.mk

	Using the 'make' command, requires that the express.mk file already
exists, and has been updated accordingly.

	If you modify the ReadDted project, and elect to specify the process
as "user" or another user-defined process, then the module may be compiled
without having to exit the AVS/Express application. Use the following command
in the VCP to compile the module:

	$compile IAC_PROJ.ReadDted.ReadDtedMods

	Users of the Developer's Edition may select the module in the 
relevant Templates library, and choose 'compile' from the Project menu.


Files
-----

The following files can be found in the iac_proj/cl_edges/ directory.

INSTALL 	Contains installation instructions for editing the iac_proj.v
		and iac_lib/ files. This file should not be edited as the
		future installation script will use this file.

rd_dted.v	Creates the IAC_PROJ.ReadDted library.

dtedmods.v	Creates the ReadDtedMods library containing the low-level
		modules ReadDtedCore and ReadDtedCoreAlt, and the parameter
		block ReadDtedParams.

dtedmacs.v	Creates the ReadDtedMacs library containing the user interface
		macros Read_Dted_UI and Read_Dted_UI_Alt, the functional macros
		Read_Dted and Read_Dted_Alt, the user macros read_dted and
		read_dted_alt, and the example application ReadDtedEg.

rd_dted.cxx	C++ source code for the ReadDtedCore module.

gs252.h		C++ source code that provides the underlying interface to the
gs252.cxx	DTED file format.

Generated Files
---------------

When the project is compiled, the following files will be generated. Once
completed, you may safely remove these files; any future recompilations
will regenerate these files.

gen.hxx		AVS/Express generated header file.

gen.cxx		AVS/Express generated source code.

rd_dted.o/obj	Intermediate object files.
gs252.o/obj
gsacc.o/obj
