ndiff is a utility for comparing putatively similar files, ignoring small
numeric differences. The utility is written by Nelson H. F. Beebe and
covered by the GNU General Public License (GPL), version 2. It may be
built with arbitrary precision support (more powerful) or using built-in
floating point precision, see Makefile.
Assessing the consistency of a numerical program run in multiple
environments (operating systems, architectures, or compilers) can be a
difficult task for a human, as small differences in numerical output values
are expected. File differencing utilites, such as diff(1), will generally
produce voluminous output, often longer than the original files.
ndiff solves this problem. Taking two text files expected to be
identical, or at least numerically similar, it allows to specify absolute
and/or relative error tolerances for differences between numerical values
in the two files, and then reports only the lines with values exceeding
those tolerances. It also tells by how much they differ. A simple example:
% ndiff --relative-error 1.0e-3 test019.txt.1 test019.txt.2
### Maximum relative error in matching lines = 8.64e-51 at line 129 field 4
===> The following configuration options are available for ndiff-2.00_5:
DOCS=on: Build and/or install documentation
GMP=off: GMP (multiple precision arithmetic) support
===> 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.

For ports maintained by ports@FreeBSD.org, remove names and/or
e-mail addresses from the pkg-descr file that could reasonably
be mistaken for maintainer contact information in order to avoid
confusion on the part of users looking for support. As a pleasant
side effect this also avoids confusion and/or frustration for people
who are no longer maintaining those ports.
. Respect hier(7).
. Use a better ALL_TARGET. Having check as part of it tried to install
some files. Use check-runs to achieve the desired testing without
doing any installation.
. ${INSTALL_MAN} -> ${INSTALL_DATA} for doc installation (they aren't
manual pages).
Deal with the libgmp dependency properly:
- Don't depend on math/libgmp-freebsd on FreeBSD <= 500023, use the base
libgmp instead. On FreeBSD > 500023 depend on math/libgmp4, as
math/libgmp-freebsd doesn't build on all architectures.
- Don't add PREFIX/include and PREFIX/lib to the search paths by default,
so on FreeBSD 4 the base libgmp is used. This protects from using one of
the libgmp ports if installed without registering a dependency on it.
- Keep from auto-detecting libgmp when WITHOUT_GMP is defined by specifying
the arithmetic to use.
Note: When using auto-detection and libgmp can't be found ndiff normally
would check for extended precision arithmetic first and succeed with it.
But using extended precision arithmetic causes the test suite to fail
(i.e. lots of differences) on all architectures expect sparc64. Therefore
specify double precision arithmetic for all other architectures when built
with WITHOUT_GMP.
