OK. I am sorry for the delay.
I hereby make the following public proclamation:
zn_poly 0.9 is released under a new license.
Replace the COPYING file in the source distribution with the following:
========================= begin

***EXCEPTIONS***
zn_poly incorporates small amounts of code from other projects, which have different licensing requirements:
The file "wide_arith.h" includes some assembly macros from the file
"longlong.h" in GMP 4.2.1; see
http://gmplib.org/. The copyright to this
code is held by the Free Software Foundation, and it was released under
"LGPL v2.1 or later".
The file "wide_arith.h" also includes assembly macros from the file
"SPMM_ASM.h" in NTL 5.4.1; see
http://www.shoup.net/ntl/. The copyright
to this code is held by Victor Shoup, and it was released under "GPL v2 or
later".
The filer "profiler.h" contains x86 cycle counting code from the file
"profiler.h" in FLINT 1.0; see
http://www.flintlib.org/. The copyright
to this code is held by William Hart, and it was released under "GPL v2 or
later".
========================= end
The various source/header files also contain licensing information in the first couple of lines. These should be changed in the obvious way to be consistent with the above statement.
I am not going to release a new tarball with these changes. Already the version on my web page is pretty out of date, it doesn't include a lot of patches that are floating around (in Sage and elsewhere).
Also anything I write on this mailing list is far more permanent than anything I put on my web page!
