[Fedora-legal-list] Xerox license

[Mamoru Tasaka]

Hello.

Now I am reviewing synopsis [1].
Some of the files in synopsis uses Xerox license as below:
-------------------------------------------------------------------------

  All Rights Reserved.

----------------------------------------------------------------------------
This seems MIT-ish, however I wonder if the terms of "compliance with
US laws" make this license GPL incompatible.
For synopsis, if this is LGPLv2+ compatible it is okay.

So would you tell me if
- this is enough Free for Fedora
- this is LGPL/GPL compatible
If this is GPL incompatible, I would appreciate it if this license is named
and added to Fedora legal wiki page.

Regards,
Mamoru
