+PocketSphinx 1.0.0 prerelease
+=============================
+
+This is PocketSphinx, one of Carnegie Mellon University's open source large
+vocabulary, speaker-independent continuous speech recognition engines.
+
+Although this was at one point a research system, active development
+has largely ceased and it has become very, very far from the state of
+the art.  I am making a release, because people are nonetheless using
+it, and there are a number of historical errors in the build system
+and API which needed to be corrected.
+
+**Please see the LICENSE file for terms of use.**
+
+Installation
+------------
+
+We now use CMake for building, which should give reasonable results
+across Linux and Windows.  Not certain about Mac OS X because I don't
+have one of those.  In addition, the audio library, which never really
+built or worked correctly on any platform at all, has simply been
+removed.
+
+There is no longer any dependency on SphinxBase, because there is no
+reason for SphinxBase to exist.  You can just link against the
+PocketSphinx library, which now includes all of its functionality.
+
+So you can do something like this:
+
+```
+mkdir build
+cd build
+cmake ..
+make
+make install
+```
