- ~~~~~~~~~~~~~~~~~~~~~~~
-
- 1. Definitions
-
- The Software means the AMPlayer module (all variants), the
- AMPlayerSelector module, documentation, etc.
-
- The Developers means the developers of The Software or their
- nominated agents.
-
- A Test Group will be a designated group of testers not to exceed
- 100 persons.
-
- A Dependent Application is a software application that makes
- use of The Software (or part of The Software) in its operation.
-
- 2. Warranty
-
- The Software is free (*) software. You use it at your own risk. It
- comes with no warranty at all.
-
- No guarantees at all are made about patent infringement; if you
- wish to use this module in any system at all, you are responsible
- for ensuring that you have licenses for any patents that may be
- required.
-
- [* under the conditions outlined below.]
-
- 3. Copyright
-
- The Software source code is Copyright (C) the Developers,
- and is freely available under the terms laid out below.
-
- 4. Distributions
-
- The Software may be released in 3 ways, as a binary distribution, a
- source distribution and a binary distribution with an application.
-
- 4.1 Binary Distributions
-
- 4.1.1 Binary distributions will from time to time be issued by
- the Developers. These will be termed 'Official Binary
- Distributions' (OBDs).
-
- 4.1.2 In addition anyone producing their own customised
- versions may produce their own 'Unofficial Binary
- Distributions' (UBDs), subject to the rules in section
- 5.
-
- These must include all the documentation supplied with
- the preceeding OBD, but must also include a prominent
- notice stating that this is an unoffical release, and
- outlining the changes made since the preceeding OBD. The
- binary module supplied must clearly identify itself in
- its module help text and title string as an unoffical
- version.
-
- UBDs may only be produced AFTER the changed source has
- been passed back to the Developers, as per section 5. UBDs
- should be removed after an OBD that incorporates its changes
- has been produced.
-
- This license will apply to any UBD made.
-
- 4.1.3 No charge (other than media costs) may be made for a binary
- distribution.
-
- 4.1.4 Binary distributions may only be made from areas of a internet
- site which does not have public access if it is to a Test Group
- or if it is also accessible on a public access site.
-
- 4.2 Source Distributions
-
- 4.2.1 Source distributions will from time to time be issued by
- the Developers. These will be termed 'Official Source
- Distributions' (OSDs).
-
- 4.2.2 In addition anyone producing their own customised
- versions may produce their own 'Unofficial Source
- Distributions' (USDs).
-
- These must include all the documentation supplied with
- the preceeding OSD, but must also include a prominent
- notice stating that this is an unofficial release, and
- outlining the changes made since the preceeding OSD. The
- binary module produced must clearly identify itself in
- its module help text and title string as an unoffical
- version.
-
- USDs may only be produced AFTER the changed source has
- been passed back to the Developers, as per section 5. USDs
- should be removed after an OSD that incorporates its changes
- has been produced.
-
- This license will apply to any USD made.
-
- 4.2.3 No charge (other than media costs) may be made for a binary
- distribution.
-
- 4.2.4 Source distributions may only be made from areas of a internet
- site which does not have public access if it is to a Test Group
- or if it is also accessible on a public access site.
-
- 4.3 Binary Distribution with a Dependent Application
-
- 4.3.1 Application authors wishing to ship the Software with a
- freeware Dependent Application into the RISC OS desktop
- market may include an OBD (or UBD until the succeeding
- OBD appears) unchanged.
-
- 4.3.2 Application authors wishing to ship the Software with a
- commercial Dependent Application into the RISC OS desktop
- market may include an OBD (or UBD until the succeeding
- OBD appears) unchanged.
-
- 4.3.3 Anyone wishing to ship the Software contrary to these
- conditions must contact the Developers for permission
- first.
-
- This includes shipping the Software on CDs (commercial or
- otherwise) or with computer systems (whether new or
- second hand).
-
- Anyone flouting these distribution rules agrees to pay 1
- million pounds sterling (or a lower amount to be agreed
- with the Developers) to a charity nominated by the
- Developers.
-
- 4.3.4 The Developers reserve the right to grant permission to
- third parties for them to distribute source or binaries
- derived from the Software with Dependent Applications
- contrary to this license as they see fit. This permission
- does not release them from their responsibilities as per
- section 5.
-
- 4.3.5 The Software may only be distributed (as an OBD, UBD,
- OSD or USD) with a Dependent Application via the Internet
- from areas of an internet site which do not have public
- access if it is to a Test Group or if the corresponding
- OBD, UBD, OSD or USD is also accessible on a public
- access site.
-
- 5. Modifications
-
- 5.1 OSDs will be made with the deliberate purpose of encouraging
- future developments. The Software source code is protected to
- the maximum amount allowable by law. Sections of the Software
- source code may not be removed from the Software and used
- elsewhere without permission of the Developers.
-
- 5.2 Any changes made to the Software source code must be passed
- back to the Developers before any release of the changed code is
- made (other than to a Test Group).
-
- 5.3 Copyright of these changes remains with the original author,
- and the Developers are granted a non-exclusive, transferrable,
- royalty free license to these changes.
-
- 5.4 Once this transfer has taken place the author of the changes
- has the right to produce UBDs and USDs as required.
-
- 5.5 After these changes have been passed back the Developers will
- consider incorporating the changes into the main Software source
- tree.
-
- 5.6 If the Developers decide to incorporate the changes supplied they
- will produce a new OBD. Wherever possible UBDs (or USBs) should be
- removed in favour of the succeeding OBD (or USD).
-
- 5.7 If the Developers decide NOT to incorporate the changes supplied
- (for whatever reason) then the author of the changes is perfectly
- entitled to carry on using the UBD (or USD).

-
- Commentary on the license
- ~~~~~~~~~~~~~~~~~~~~~~~~~
-
- This license has been designed with several aims in mind.
-
- Firstly, we want to ensure that AMPlayer is and remains free. People
- should feel confident enough to build applications that use it
- without fear of having the right to use it removed from them.
-
- Secondly, we want people to realise it has no warranty. If its useful,
- great. If it eats your harddisc, tough. We've done our best, but we
- make no promises.
-
- Thirdly, we want a license that recognises the amount of work that has
- gone into AMPlayer - we are quite happy for people to use AMPlayer in
- commercial systems on RISC OS, but if you are going to take it to
- another platform we want to have a say in that. Furthermore if you
- want to pull AMPlayer to bits and build something else from it, we'd
- like a say in that too.
-
- Thats not to say we won't approve the idea, just that we'd like to be
- consulted.
-
- Fourthly, we would like to see AMPlayer continue to develop; people
- should be granted the freedom to make changes and to distribute those
- changes. But just because you make a change doesn't mean we should
- lose our control over the software.
-
- We would rather not see a huge proliferation of incompatible versions,
- which is why we insist that code changes are submitted to us for us to
- merge into the main tree. On the other hand, we don't want people to
- feel that they are being unduly limited in producing versions of
- AMPlayer that do what they want - hence the freedom for anyone to
- produce UBDs and USDs. They just can't call them official releases.
-
- This also protects everyone else if we (the AMPlayer developers)
- suddenly stop work. There would still be a route for other keen programmers
- to get versions out there (albeit unofficial ones).
