BSD 4-Clause

[jakirkham]

Noticed that the license is BSD 4-Clause. Was curious if the intent was to have a BSD 4-Clause or simply some BSD license was desired and this one was picked.

If it was the latter, it's worth noting that the advertising clause was deemed problematic by GNU and Berkeley eventually removed it. Usually people wanting a BSD license go with BSD 3-Clause or BSD 2-Clause when picking a BSD license these days to avoid these issues.

If choosing BSD 4-Clause was intentional, would be curious to know why BSD 4-Clause was picked in this case.

Note: IANAL
