Changes in this release:
* Headers are now in ${PREFIX}/include/speex/ (but a copy is still in
${PREFIX}/include for compat reasons).
* Pseudo-gapless playback (i.e. playback has the same number of samples).
* Fixed a potential bug (unconfirmed) that might cause a segfault
in special circumstances.
Speex is a patent-free audio codec designed especially for voice
(unlike Vorbis which targets general audio) signals and providing
good narrowband and wideband quality. This project aims to be
complementary to the Vorbis codec.
