I think one has to package everything inside 'abcl.jar', placing your 
code in the 'org.armedbear.lisp' directory.  This should be what 
*LISP-HOME* gets set to.  I have yet to get enough time to figure out 
how to deploy to Google App Engine (GAE) myself:  it's on a long TODO 
list which got pushed further down with having to figure out how to use 
the Eclipse plugin to deploy to GAE.
