CRlibm is an efficient and proven mathematical library, which
provides implementations of the double-precision C99 standard
elementary functions, correctly rounded in the four IEEE-754 rounding
modes, and sufficiently efficient in average time, worst-case time,
and memory consumption to replace existing libms transparently.
The distribution includes extensive documentation with the proof
of each function (currently more than 100 pages), as well as all
the Maple scripts used to develop the functions. This makes this
library an excellent tutorial on software elementary function
development.
CRlibm also includes a lightweight library for multiple precision,
scslib (Software Carry Save Library). This library has been developed
specifically to answer the needs of the CRlibm project: precision
up to a few hundred bits, portability, compatibility with IEEE
floating-point standards, performance comparable to or better than
GMP, and a small footprint. It uses a data-structure which allows
carry propagations to be avoided during multiple-precision
multiplications, and supports addition, subtraction, multiplication,
and conversions.
===> The following configuration options are available for crlibm-1.0.b4_2:
DOCS=on: Build and/or install documentation
EXTRA_TEST=on: Include all test capabilities (requires MPFR)
===> Use 'make config' to modify these settings
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.

Remove OSVERSION checks that do not make sense any more.
For example (${OSVERSION} >= 900000 && ${OSVERSION} < 900021) is always true,
as is (${OSVERSION} > 900002 || ${OSVERSION} < 900000 && ${OSVERSION} > 800107).
Regarding patches, when an EXTRA_PATCHES is no longer needed, I remove it, when
it is always needed, I renamed it, in one case, I merged two patches.
Differential Revision: https://reviews.freebsd.org/D2209
use archive in unmodified form; make the MPFR dependency optional;
compile test executables with appropriate flags; enable SSE2 math
by default when possible
