 Maintainer Notes:
-* REPLACED gson-2.2.4.jar with source-build 2.2.4 from upstream.
-* REPLACED ejml-0.21.jar with source-build 0.25 from upsteam.
-* REPLACED arity-2.1.6.jar with source-build from app author as upstream is no longer available.
-# REPLACED gdk.jar with file from Android Glass Development Kit.
-* REMOVED gdk.jar and removed references from source.
-* REPLACED slider.jar with source-build latest from upstream
-* REMOVED wearable-preview-support.jar -- builds, but does it run?
+The JAR files slider.jar, gson-2.2.4.jar and ejml-0.21.jar have been replaced
+by a version build from upstream sources. As arity-2.1.6.jar is no longer
+available from upstream, it has been replaced by a repo-copy of the author
+of this app.
+
+Google's Glass Development Kit is currently not available under a free license,
+so $$SDK$$/add-ons/addon-google_gdk-google-19/libs/gdk.jar cannot be used. It
+hhas been removed and the code has been patched to not use it.
+
+Google's wearable-preview-support.jar is currently not available under a free
+license. It seems like it's not used in this version, so it has been removed.
