bugfix release

Changes:
- updated manpage
- check if output file exists; --overwrite option added
- help/usage options reorganized
- block switching is now tuned to match quality/bitrate
- give more quality to lower frequancies (less to highs)
- quantizer updated again

Changes:

- rewritten quantizer: faster, diffrerent quality, different bitrates
- ftyp atom: set brands like itunes does, shoud be more compatible
  with picky tools
- new option(--tag) to add named tags (iTunes '----')
- faster and better short/long window type switch
- Don't build DRM(Digital Radio Mondiale) by default.
  Use ./configure --enable-drm to build DRM version.
- fixed bugs
  * rounding in QuantizeReflectionCoeffs (tns.c)
  * use +60 value for scalefactor.
  * use clipped diff instead of original value (huffman.c)

Changes:
- MP4 tag options improved
- fixed MP4 'meta' atom bug
- new option to set verbosity (-v0 to silence output)

New in this release is completely new mp4 output formatter.
And as usual many small things fixed.

Release of FAAD2 version 2.6.1
* Updated the copyright header so there is no more confusion about GPLv2 compatibility
* Minor bugfixes
* Third party committed AD Blackfin support

FAAD2 2.5 source code is now available from http://www.audiocoding.com/
No big news, just bugfixes.

Final 2.0 version. Only small bugfixes since RC3.

The FAAC project is releasing the Release Candidate 3 version of FAAD2 2.0.

These are the changes since Release Candidate 1:

ChangeLog:
Accuracy increased to 24 bits
30% total speedup
Memory usage lowered a lot
Fixed point decoding speedup
SBR conformance fixes
MAIN decoding fixed
fixes in TNS

Source packages and a precompiled MP4 Winamp plugin are available at the Files section.

(Release Candidate 2 was quickly replaced with Release Candidate 3 after a channel coupling bug was detected in the SBR routines)

FAAD2 2.0 is now available as Release Candidate 1. The most important new feature is the support for the HE AAC profile (HE=high efficiency).

HE AAC is the joining of MPEG4 AAC with SBR - the well know technology used in MP3pro - to create the perceptually best audio encoder for low bitrates (less than 80kbps)

Formal listening tests conduced by the MPEG demonstrate that HE AAC offers excellent quality for non-critical listening on bitrates around 48~64kbps.... read more

Version 1.5 of both FAAC and FAAD are released. These versions are completely compatible with the MPEG2 and MPEG4 AAC standard.
This is the only AAC codec available for free. Both encoder and decoder come as easy to use, well documented libraries.
FAAD is the fastest available AAC decoder.
