To me it looks like Expat, with the following changes:
to deal in the Software without restriction, including without
limitation the rights to use, copy, modify, merge, publish,
distribute, sublicense, and/or sell copies of the Software
to use the Software as part of another work; to modify it for that
purpose; to publish or distribute it, modified or not, for that same
2) “this permission notice” changed to “this complete and unmodified
3) added “You will not misrepresent modified versions of the Software
as being the original.”
4) removed capitalisation of the no-warranty text.
The requirement to use IBPP only as part of another work is so easily
worked-around, that is practically of no legal value. Not that see any
problem with it.
Olivier, is this the intented license for IBPP 2.5?
If yes, I should consult once again with debian-legal (just in case).
