Terms and Conditions for the use of the Netwide Assembler
=========================================================

Can I have the gist without reading the legalese?
-------------------------------------------------

Basically, NASM is free. You can't charge for it. You can copy it as
much as you like. You can incorporate it, or bits of it, into other
free programs if you want. (But we want to know about it if you do,
and we want to be mentioned in the credits.) We may well allow you
to incorporate it into commercial software too, but we'll probably
demand some money for it, and we'll certainly demand to be given
credit. And in extreme cases (although I can't immediately think of
a reason we might actually want to do this) we may refuse to let you
do it at all.

NASM LICENCE AGREEMENT
======================

By "the Software" this licence refers to the complete contents of
the NASM archive, excluding this licence document itself, and
excluding the contents of the `test' directory. The Netwide
Disassembler, NDISASM, is specifically included under this licence.

I. The Software is freely redistributable; anyone may copy the
Software, or parts of the Software, and give away as many copies as
they like to anyone, as long as this licence document is kept with
the Software. Charging a fee for the Software is prohibited,
although a fee may be charged for the act of transferring a copy,
and you can offer warranty protection and charge a fee for that.

II. The Software, or parts thereof, may be incorporated into other
freely redistributable software (by which we mean software that may
be obtained free of charge) without requiring permission from the
authors, as long as due credit is given to the authors of the
Software in the resulting work, as long as the authors are informed
of this action if possible, and as long as those parts of the
Software that are used remain under this licence.

III. Modified forms of the Software may be created and distributed
as long as the authors are informed of this action if possible, as
long as the resulting work remains under this licence, as long as
the modified form of the Software is distributed with documentation
which still gives credit to the original authors of the Software,
and as long as the modified form of the Software is distributed with
a clear statement that it is not the original form of the Software
in the form that it was distributed by the authors.

IV. The Software, or parts thereof, may be incorporated into other
software which is not freely redistributable (i.e. software for
which a fee is charged), as long as permission is granted from the
authors of the Software. The authors reserve the right to grant this
permission only for a fee, which may at our option take the form of
royalty payments. The authors also reserve the right to refuse to
grant permission if they deem it necessary. For further information
about who exactly the authors are, see clause XI below.

V. The Software may be incorporated, in its original archive form,
into software collections or archives which are not freely
redistributable, as long as it is clearly stated that the Software
itself remains freely redistributable and remains under this licence
and no other. Such collections are deemed not to fall under article
IV of this licence.

VI. Object files or programs generated by the Software as output do
not fall under this licence at all, and may be placed under any
licence the author wishes. The authors explicitly lay no claim to,
and assert no rights over, any programs written by other people and
assembled into object form by the Software.

VII. You may not copy, modify or distribute the Software except
under the terms given in this licence document. You may not
sublicense the Software or in any way place it under any other
licence than this one. Since you have not signed this licence, you
are not of course required to accept it; however, no other licence
applies to the Software, and nothing else grants you any permission
to copy, modify, sublicense or distribute the Software in any way.
These actions are therefore prohibited if you do not accept this
licence.

VIII. There is no warranty for the Software, to the extent permitted
by applicable law. The authors provide the Software "as is" without
warranty of any kind, either expressed or implied, including but not
limited to the implied warranties of merchantability and fitness for
a particular purpose. The entire risk as to the quality and
performance of the Software is with you. Should the Software prove
defective, you assume the cost of all necessary servicing, repair or
correction.

IX. In no event, unless required by applicable law or agreed to in
writing, will any of the authors be liable to you for damages,
including any general, special, incidental or consequential damages,
arising out of the use or the inability to use the Software,
including but not limited to loss of data or data being rendered
inaccurate or a failure of the Software to operate with any other
programs, even if you have been advised of the possibility of such
damages.

X. In addition to what this Licence otherwise provides, the Software
may be distributed in such a way as to be compliant with the GNU
General Public Licence, as published by the Free Software Foundation,
Cambridge, MA, USA; version 2, or, at your option, any later version;
incorporated herein by reference.  You must include a copy of this
Licence with such distribution.  Furthermore, patches sent to the
authors for the purpose of inclusion in the official release version
are considered cleared for release under the full terms of this
Licence.

XI. The authors of NASM are the original authors (Simon Tatham and
Julian Hall) and all those who the original authors feel have
contributed significantly to the overall project.  If you wish to
contact the authors, Julian Hall (jules@earthcorp.com) should be your
first port of call.

XII. Should any part of this agreement be deemed unenforcable, it is
intended that the remainder of the agreement be held in force.
