That's clause 3 from the so-called "old BSD" license. UC/Berkeley and most other BSD contributors have waived it in favor of the 2-clause or new BSD license.

Not on each page, no. And not for most of the software which is under the 2-clause license. However, you do need to preserve notices for software under the BSD 3-clause license once on your website, in the manual or README. > - The 4-clause of the license says: "Neither the name of <name> nor the > names of its contributors may be used to endorse or promote products > derived from this software without specific prior written permission.".

No, that would be a standard acknowledgement of origin. The no-endorsement-clause restricts folks from claiming that UC/Berkeley, the FreeBSD project, etc endorse your modified version of the software. > - Does the main COPYRIGHT file overwrite other author licenses? No. But most FreeBSD contributors have agreed to use the 2-clause format. Regards, -- -Chuck
