Subject: Remove libresample from the Asterisk source tree.  It is now
 available in its own repository, and must be installed like any other library
 for Asterisk to use.  The two modules that require it are codec_resample and
 app_jack.

To install libresample:

$ svn co http://svn.digium.com/svn/libresample/trunk libresample
$ cd libresample
$ ./configure
$ make
$ sudo make install

This code is currently in our own repository because the build system did not
include the appropriate targets for building a dynamic library or for installing
the library.
