FDC 1.3, License Agreement                    (No changes since October 1997)
==========================                    -------------------------------

* USING THIS SOFTWARE IMPLIES THAT YOU AGREE WITH THE RULES FROM THIS LICENSE.

* All software written by M.O. Rauw which is part of the FDC toolbox may be
  used without restrictions.

* The software written by M.O. Rauw which is part of the FDC toolbox may only
  be distributed in UNCHANGED and COMPLETE form, including all the files
  listed in CONTENTS.TXT, and only if this is done WITHOUT charge. If you
  want to distribute only parts of the FDC toolbox or charge a fee for
  handling, etc., you have to contact the author. In particular, commercial
  distribution on diskette or CD ROM is prohibited without explicit
  permission.

* Any custom-made extensions to the FDC package should be distributed sepa-
  rately, using file names that differ from the original FDC package.
  Inclusion of extensions to the original FDC distribution diskettes is
  prohibited without explicit permission from the author.

* Elements from the FDC tools or systems may be included in other programs
  and systems, provided the original source (e.g. 'FDC 1.3 by M.O. Rauw') is
  referred to in the resulting source codes. Distribution of customized
  systems and tools from the FDC toolbox is allowed only if the differences
  from the original version are clearly marked.

* Distribution of the program documentation other than that included in the
  FDC distribution package is prohibited without explicit permission from the
  author.

* No guarantee is made as to the proper functioning of the FDC software. No
  liability will be admitted for damage resulting from using the software.

* Instead of a list: All trademarks used in this document and all the other
  documents and program files from the FDC toolbox are registered to whoever
  it is that owns them.


Why are these license rules necessary?
======================================
The basic philosophy behind these license rules is that the FDC toolbox
should be a system which can be trusted by users of all types to fulfill
their needs, while at the same time providing a maximum flexibility for the
user to experiment with the contents of the FDC files. It is not possible
to ensure compatibility between different Simulink (sub-) systems and
Matlab programs from the FDC toolbox if different versions of the systems
and tools are distributed under the same names. For instance, altering the
definitions of the input and output vectors within the existing aircraft
model BEAVER.M will render the current systems which call BEAVER.M as a
subsystem useless, unless those systems are changed accordingly. This may
not be a problem for an individual user who can easily keep track of all
changes made to the programs and systems, but if the models are shared with
other users - which is the ultimate goal of the modular FDC structure -
unexpected errors will arise. In the same way errors may arise if different
versions of FDC files are distributed under their original names.

For this reason, the license rules only allow distribution of the complete,
original distribution files of the FDC toolbox. The user is free to release
custom-made versions and add-ons to the FDC toolbox, under the condition
that these changes and extensions are clearly marked as being different
from the original FDC toolbox. Such extensions may therefore NOT be
included to the original FDC distribution diskettes, and different
file-names should be used. These rules are not intended to discourage the
user in experimenting with the programs and Simulink models from the FDC
toolbox. It is allowed to use the existing files or separate elements from
these files as 'templates' for own developments, as long as the original
source is mentioned in the new version and a new file-name is used for
distribution.

Of course, I appreciate any contributions to the FDC package and if you
think you have any useful ideas for future versions of the package, please
let me know. If possible, I will include your ideas in future versions of
the FDC package. In principle, every new contribution will be distributed
under the same license rules as the current package; if you do not agree
with these rules you should include your own license agreement to your
contribution.
