curses.buildlink2.mk. This was wrong because we _really_ do want to
express that we want _n_curses when we include the buildlink2.mk file.
We should have a better way to say that the NetBSD curses doesn't
quite work well enough. In fact, it's far better to depend on ncurses
by default, and exceptionally note when it's okay to use NetBSD curses
for specific packages. We will look into this again in the future.

Update requested by Brad Forschinger <bnjf@optushome.com.au> in private mail.
Changes since 3.89:
* Darin Morrison: Bugfix for --alt-preset (for content with low volume,
clean vocals), only important for the "fast standard" preset
* Alexander Leidinger: <BR
* add some missing files to the distribution
* add --alt-preset to the man page
* Many small improvements and bug fixes not added to history
* John Dahlstrom: more fine tuning on the auto adjustment of the ATH
* Robert Hegemann: small speed and quality improvements for the old VBR
code (--vbr-old).
* Robert Hegemann: some short block bug fixes
* Robert Hegemann: Big improvements to --vbr-mtrh, now encodes much
more frequencies over 16khz
* Robert Hegemann: --vbr-new code disabled (outdated and lower quality)
and replaced with --vbr-mtrh (Both --vbr-new and --vbr-mtrh now
default to mtrh)
* Robert Hegemann: reordering of --longhelp to give more information,
--extrahelp dropped
* Darin Morrison: Totally revamped and extremely high quality unified
preset system and other general quality improvements now available
with --alt-presets:
* some improvements to psychoacoustics (vast improvements over
default L.A.M.E. modes) when --alt-preset is used including:
* Improved tuning of short block usage.
* Improved quantization selection usage (the -X modes), now
adapts between appropriate modes on the fly. Also helps on
"dropout" problems and with pre-echo cases.
* Improved joint stereo usage. Thresholds are better tuned now
and fix some "dropout" problems L.A.M.E. suffers from on
clips like serioustrouble.
* Improved noise shaping usage. Now switches between noise
shaping modes on the fly (toggles -Z on and off when
appropriate) which allows lower bitrates but without the
quality compromise.
* Clips vastly improved over default L.A.M.E. modes
(vbr/cbr/abr, including --r3mix): castanets, florida_seq,
death2, fatboy, spahm, gbtinc, ravebase, short, florida_seq,
hihat, bassdrum, 2nd_vent_clip, serioustrouble, bloodline,
and others. No degraded clips known.
* VBR bitrates are now more "stable" with less fluctuation --
not dipping too low on some music and not increasing too
high unnecessarily on other music. "--alt-preset standard"
provides bitrates roughly within the range of 180-220kbps,
often averaging close to 192kbps.
* --alt-presets replace the --dm-presets and "metal" preset is
removed and replaced with generic abr and cbr presets.
* --alt-preset extreme (note the 'e') replaces xtreme to help
eliminate some confusion
* --alt-preset vbr modes now have a fast option which offers almost
no compromise in speed.
* --alt-preset standard (and "fast standard") are now much lower in
bitrate, matching --r3mix with an overall average, though
offering higher quality especially on difficult test samples.
* --alt-presets are no longer just "presets" as in a collection of
switches, instead they are now quality "modes" because of special
code level tunings (those mentioned above).
* Use --alt-preset help for more information.
* Roel VdB: more tuning on the --r3mix preset
* Jon Dee, Roel VdB: INFO tag
* Alexander Leidinger, mp3gain@hotmail.com: added --scale-l and
--scale-r to scale stereo channels independantly
* Takehiro Tominaga: new noise shaping mode, offering more "cutting
edge" shaping according to masking, enabled via -q1
* Mark Taylor: More work on --nogap
* Gabriel Bouvigne: Small changes to abr code for more accurate final
bitrate
* Gabriel Bouvigne, mp3gain@hotmail.com: Preliminary ReplayGain
analysis code added (not functional yet)
* Gabriel Bouvigne, Alexander Leidinger: Documentation updates
* John Dahlstrom, DSPguru@math.com: floating point interface function
in the Windows DLL
foo-* to foo-[0-9]*. This is to cause the dependencies to match only the
packages whose base package name is "foo", and not those named "foo-bar".
A concrete example is p5-Net-* matching p5-Net-DNS as well as p5-Net. Also
change dependency examples in Packages.txt to reflect this.
pkgsrc related changes:
-use default install, so we get the library installed too
(needed eg. as audacity plugin)
-this version knows about libffm (on alpha), removed corresponding
patches (untested)
changelog:
LAME 3.89alpha July 5 2001
John Stewart: long filename support for Win9x/NT.
Takehiro Tominaga: LAME can calculate the CRC of VBR header, so now
"lame -pv" works fine.
Robert Hegemann: Improvements of the new VBR code.
Robert Hegemann: New VBR code is now defaulted. The VBR speed is now on par
with CBR. We will use the old VBR code in the release.
Gabriel Bouvigne: Change of the maximum frame size limit. LAME should now
be more friendly with hardware players.
Gabriel Bouvigne: Size of VBR is now more balanced according to
the -V value.
Alexander Leidinger: Finished the implementation of the set/get functions.
John Dahlstrom: LAME now handles 24bits input
Mark Taylor: bugs in lame --decode causing truncation of mp3 file fixed
Mark Taylor: preliminary --nogap support
"Final" API completed: shared library safe! This API is frozen and should
be backwords compatiable with future versions of libmp3lame.so, but we
will continue to add new functionality.
LAME 3.88beta March 25 2001
A lot of work that was never added to the History!
Frank Klemm and Gabriel Bouvigne: New ATH formula. Big improvement for
high bitrate encodings.
Takehiro Tominaga: Temporal masking
Gabriel Bouvigne/Mark Taylor: auto adjustment of ATH
Robert Hegemann: Better outer_loop stopping criterion. Enabled
with -q2 or better.
Robert Hegemann/Naoki Shibata: slow/carefull noise shaping.
-q3..9: amplify all distorted bands.
-q2: amplify distorted bands within 50%.
-q1-0: amplify only most distorted band at each iteration.
Takehiro Tominaga: Interframe, shortblock temporal masking.
Takehiro Tominaga: LAME restructured into a shared library and front end
application. Slight changes to the API. More changes are coming to
turn LAME into a true shared library (right now you have to recompile
if you upgrade the library :-(
Naoki Shibata:
improvements to psychoacoustics (--nspsytune)
BUG in long block pre echo control fixed (some out of range array
access in M/S psychoacoustics)
Ralf Kempkens: Visual Basic Script for lame, suggested to put it on your
Windows Desktop and you can drag'n'drop Waves to encode on it.
Alexander Stumpf: improved lame.bat for 4Dos users
Mark Taylor: Several bugs fixed in the resampling code.
Frank Klemm, Robert Hegemann: added assembler code for CPU feature
detection on runtime (MMX, 3DNow, SIMD)
Takehiro Tominaga: 3DNow FFT code.
Florian Bome, Alexander Leidinger: more work on configure stuff
Alexander Leidinger: automake/libtool generated Makefiles and TONS of
other work.
Alexander Leidinger: Much work towards shared library style API.
Anonymous: New more efficient RTP code.
Mark Taylor: psycho-acoustic data now computed for all scalefactor bands
(up to 24khz)
Mark Taylor, Takehiro Tominaga: All ISO table data replaced by formulas -
should improve MPEG2.5 results for which we never had correct
table data.
instead; install more documentation.
Lame isn't any longer a patch against the ISO source, but stand-alone.
Other changes:
MP3 decoding support, ID3V2 support, vorbis support (not compiled in
right now), MPEG2.5 support; lots of bugfixes and speedups (for
details, see installed history.html).
While there, split (again...) into lame and lame-gui package.
Many speed ups, bug fixes, quality improvements and
added functionality (eg. ID3 tags, VBR histogram).
