ABC is a growing software system for synthesis and verification of binary
sequential logic circuits appearing in synchronous hardware designs. ABC
combines scalable logic optimization based on And-Inverter Graphs (AIGs),
optimal-delay DAG-based technology mapping for look-up tables and standard
cells, and innovative algorithms for sequential synthesis and verification.
ABC provides an experimental implementation of these algorithms and a
programming environment for building similar applications. Future development
will focus on improving the algorithms and making most of the packages
stand-alone. This will allow the user to customize ABC for their needs as if
it were a tool-box rather than a complete tool.

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.
