the BSD license was exactly like ISC's is now, when we first copied it.
in the years since then the UC Regents have thought about things like
advertising and have added and deleted various clauses.  ISC hasn't
thought about that stuff, and the original BSD license is just fine for
our needs.

well, yes, except that those were added after our license fork, and were
never present here, and were never deleted here.  we probably started with
the 4.2BSD license.  alas, i do not have the 4.2BSD sources, nor any system
running that code where i can look at /usr/include for an example.  anybody?
(it's also dimly possible that we forked an old MIT X license, which was at
that time identical to the BSD license, and may well still be for all i know.)

odd that they got the names wrong.  ISC at the time this license was forked
was "internet software consortium".  today's "internet systems consortium" is
the successor-in-interest to the old "internet software consortium" but the
name of the entity who forked this license is the old name not the new name.

that wikipedia entry also refers to an FSF question, which turned up some
interesting ugliness with the word "and" in the first sentence, as abused by
somebody in some other project.  we're going to say "and/or" from now on, to
remove any possible concern or confusion about what we meant by "and".  i
hate this kind of thing, it reminds me that lawyers used to get paid by the
word.  "never use two words when one will."  and so on.

depends on which side of the road you drive on, i guess.
