Issue number: Various -- I will update them
Obtained from: Submitted by: Travis Reviewed by: Committing in . Added Files: src/demos/misc/VersionInfo.java This example uses the java.lang.Package API to query the version and implementation information from the jogl.jar manifest. We will be bumping the manifest info for subsequent releases. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/../svn-server-sync/jogl-demos/trunk@169 3298f667-5e0e-4b4a-8ed4-a3559d26a5f4
