If you first do
(from the top-level directory of the source-code tree), you can then
cd to any application and run 'make' to build it.

You can strip out debug_info afterwards by running beam_lib:strip/1.
That's what I do in Wings 3D (http://wings3d.com). The source code
package for Wings 3D contains scripts and Erlang code to package the
Wings 3D application and the necessary part of Erlang/OTP into as
small package as possible (for Mac OS X, Linux, and Windows). Those
scripts could be an useful starting point for packaging your application.
