Dear Penny,

first of all let me just clarify that DEP-5 is only a proposal now, and that it
can be subjected to many changes before it is accepted.

One of the changes that I would like to propose when I have enough time to
draft a patch, is to introduce a syntax for licenses ‘similar to’ other
licenses, when they were derived from a very common license by only changing
some people, company or brand names.

As Don explained, there is only one BSD license, the one where the regents of
the university of California are coyright holders. And since they used their
copy rights to change the license in the past, there is no program that is
licensed under the ‘old BSD’ license. Nevertheless, there are some that have
license similar to it, and were not affected by the removal of the
advertisement clause because the copyright holder is not the same.

Whichever solution is adopted in DEP-5 to underline that license A is derived
from license B, unless your program is part of the BSD distribution and is
copyright by the regents of the university of California, you can not use
the copy in /usr/share/common-license and have to include it verbatim. Luckily,
it is short :)

Have a nice day,
