XAnalyser is a program to analyse a stereo audio signal. It has two displays:
Frequency Spectrum
Using Fast Fourier Transform, the time domain of the signal is transformed into
the frequency domain, i.e. the amplitude (in logarithmic scale) of the
audio signal is plotted versus the frequency. Either the sum of the
left and right channel of the audio signal can be shown or both
channels simultaneously.
XY Scope
Roughly speaking, the audio signal of left channel deflects a point
horizontally and the right channel vertically (just as the beam of a CRT
would do). Thus, an audio signal only present on the left channel produces
a horizontal line, whereas an audio signal only present on the right channel
produces a vertical line. A mono signal produces a 45 degree line.
A stereo signal creates a wilde pattern (if the phase is correct,
predominately in the same direction as a mono signal) or may even fill
the entire scope.
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.

libXp is being deprecated.
Also fixed Makefile to properly patch xanalyser.spec.in
Replaced hard coded /usr/local in favour of PREFIX and LOCALBASE as needed

audio/xanalyser: fix a ioctl call (now for real)
- SNDCTL_DSP_GETBLKSIZE() is in FreeBSD a read only ioctl()
Need to use SNDCTL_DSP_SETBLKSIZE() to really set the blocksize.

MASTER_SITES cleanup.
- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.
While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.
Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

Update CONFIGURE_ARGS for how we pass CONFIGURE_TARGET to configure script.
Specifically, newer autoconf (> 2.13) has different semantic of the
configure target. In short, one should use --build=CONFIGURE_TARGET
instead of CONFIGURE_TARGET directly. Otherwise, you will get a warning
and the old semantic may be removed in later autoconf releases.
To workaround this issue, many ports hack the CONFIGURE_TARGET variable
so that it contains the ``--build='' prefix.
To solve this issue, under the fact that some ports still have
configure script generated by the old autoconf, we use runtime detection
in the do-configure target so that the proper argument can be used.
Changes to Mk/*:
- Add runtime detection magic in bsd.port.mk
(Only the first 15 lines of the commit message are shown above )
- Set --mandir and --infodir in CONFIGURE_ARGS if the configure script
supports them. This is determined by running ``configure --help'' in
do-configure target and set the shell variable _LATE_CONFIGURE_ARGS
which is then passed to CONFIGURE_ARGS.
- Remove --mandir and --infodir in ports' Makefile where applicable
Few ports use REINPLACE_CMD to achieve the same effect, remove them too.
- Correct some manual pages location from PREFIX/man to MANPREFIX/man
- Define INFO_PATH where necessary
- Document that .info files are installed in a subdirectory relative to
PREFIX/INFO_PATH and slightly change add-plist-info to use INFO_PATH and
subdirectory detection.
