 ScripBuildPhases sample code

 Description: 
 
 This sample shows how to augment Project Builder build phases with scripts of your own, using build settings variables that will be expanded at compiletime, to do extra work and invoke other tools for processing.  In this particular sample, a java applet is compiled by Project Builder, and then a script in a shell script build phase does some post-processing to generate Palm OS executables that will run under the Superwaba handheld Java VM (obtainable from <http://www.superwaba.org> - download the SDK package). 
 
 This file provides the java source code that will have further post-processing
 performed on it after normal java compilation in Project Builder via the postprocessing.sh script
 and a shell script build phase (see the Build Phases section of the Targets pane). Any extra
 compilation or work you want done on files can be done in a shell script build phase, and such
 build phases don't have to go at the end of the build process like the one does here.  This gives
 you the developer a tremendous amount of power and flexibility! This particular java
 source code file is meant to run from the open source superwaba PalmOS/handheld device Java VM - see <http://www.superwaba.org> for download info (get the complete SDK, not just the VM).  The shell script expects that the superwaba folder/executables/classes will be placed at the root level ("/") of your boot volume, but you could edit the script to look for superwaba somewhere else.
