END OF ACADEMIC FREE LICENSE. The following is intended to describe the essential

differences between the Academic Free License (AFL) version 1.0 and other open source

licenses:

The Academic Free License is similar to the BSD, MIT, UoI/NCSA and Apache licenses in

many respects but it is intended to solve a few problems with those licenses.

* The AFL is written so as to make it clear what software is being licensed (by the inclusion

of a statement following the copyright notice in the software). This way, the license

functions better than a template license. The BSD, MIT and UoI/NCSA licenses apply to

unidentified software.

* The AFL contains a complete copyright grant to the software. The BSD and Apache

licenses are vague and incomplete in that respect.

* The AFL contains a complete patent grant to the software. The BSD, MIT, UoI/NCSA and

Apache licenses rely on an implied patent license and contain no explicit patent grant.

* The AFL makes it clear that no trademark rights are granted to the licensor's trademarks.

The Apache license contains such a provision, but the BSD, MIT and UoI/NCSA licenses

do not.

* The AFL includes the warranty by the licensor that it either owns the copyright or that it

is distributing the software under a license. None of the other licenses contain that

warranty. All other warranties are disclaimed, as is the case for the other licenses.

* The AFL is itself copyrighted (with the right granted to copy and distribute without

modification). This ensures that the owner of the copyright to the license will control

changes. The Apache license contains a copyright notice, but the BSD, MIT and

UoI/NCSA licenses do not.
