 Usage: $name { build | manifest }
For compiling aspectjtools-aj.jar using ajc, generate build/aspectjtools.lst  
and files it refers to, aspectjtools-sources.lst and aspectj-resources.jar.  

To add to aspectjtools.jar a meta-inf/manifest.mf with a main-class, 
specify a single argument: "manifest"

To create the .lst file, use ajc to build, and add the manifest,
define ASPECTJ_HOME and specify a single argument: "build"
