The PAL library is a partial re-implementation of Pat Wallace's popular SLALIB
library written in C using a Gnu GPL license and layered on top of the IAU's
SOFA library (or the BSD-licensed ERFA) where appropriate. PAL attempts to stick
to the SLA C API where possible although palObs() has a more C-like API than the
equivalent slaObs() function. In most cases it is enough to simply change the
function prefix of a routine in order to link against PAL rather than SLALIB.
Routines calling SOFA use modern notation and precession models so will return
slightly different answers than native SLALIB. PAL functions not available in
SOFA were ported from the Fortran version of SLALIB that ships as part of the
Starlink software and uses a GPL licence.
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.
