4ti2 is a software package for algebraic, geometric and combinatorial problems
on linear spaces. It computes
* the circuits of a cone
* a problem matrix corresponding to graphical statistical models
* generators for the symmetry group acting on 4-way tables
* the Graver basis of a matrix or a given lattice
* a Groebner basis of the toric ideal of a matrix or, more general, of the
lattice ideal of a lattice
* a Markov basis (generating set) of the toric ideal
* the minimal solution of an integer linear program or, more general, a lattice
program, using a Groebner basis
* the normal form of a list of feasible points
* the primitive partition identities, that is, the Graver basis of [1 2 3 ... N]
* a generator description of a cone
* the extreme rays of a cone
* an integer lattice basis
* solutions of linear inequality and equation systems over the integers

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.
