AMGCL is a header-only C++ library for solving large sparse linear systems with
algebraic multigrid (AMG) method. AMG is one of the most effective iterative
methods for solution of equation systems arising, for example, from discretizing
PDEs on unstructured grids. The method can be used as a black-box solver for
various computational problems, since it does not require any information about
the underlying geometry. AMG is often used not as a standalone solver but as a
preconditioner within an iterative solver (e.g. Conjugate Gradients, BiCGStab,
or GMRES).
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.
