Pynac -- "Python is Not a CAS" is a modified version of Ginac that
replaces the depency of GiNaC on CLN by a dependency instead of Python.
It is a lite version of GiNaC as well, not implementing all the features
of the full GiNaC, and it is *only* meant to be used as a Python library.
Note: since Sage-9.5, Pynac has been merged into the Sage library source code.
===> The following configuration options are available for pynac-0.7.29_1:
GIAC=off: Use giac for polynomial manipulations
===> Use 'make config' to modify these settings
math/pynac: Deprecate and set expiration date to 2022-12-31
Deprecated upstream as project merged with SageMath (Sage 9.5) in 2021

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.

Adding pynac, a derivative of the C++ library GiNaC, which allows manipulation
of symbolic expressions.
It currently provides the backend for symbolic expressions in SageMath.
