Here's an attempt at public consumption....

There's two files, to run them one will need to export a variable
containing the PREFIX (we are using STARGATE_HOME)  (see the 9th line
of addeapi.py).  Also the emegeparts.py file is the dependency
generation stuff.  I add portage to sys.path at the top and am
hardcoding that value...(so one will need to update that).

Now with both files in the same directory, call something like:
python addeapi.py -e eclipse-core
which will take the ebuild for eclipse-core from PORTDIR and copy it
into an overlay.  It will add EAPI="prefix", update EDEST and digest
it.

Send feedback comments my way.

On that note, we have quite a few java components added to prefix:
ant                  commons-el          jakarta-regexp    saxpath
ant-core             commons-fileupload  java-config       servletapi
ant-tasks            commons-httpclient  javacup           struts
antlr                commons-lang        jaxen             struts-legacy
avalon-logkit        commons-launcher    jdepend           sun-jaf-bin
bcel                 commons-logging     jdom              sun-jdk
bsf                  commons-modeler     jsch              sun-jmx
bsh                  commons-net         junit             xalan
commons-beanutils    commons-pool        jython            xerces
commons-collections  commons-validator   jzlib             xjavac
commons-daemon       dom4j               libreadline-java  xml-commons
commons-dbcp         gnu-crypto          log4j             xml-commons-external
commons-digester     jakarta-oro         rhino             xml-commons-resolver

Where can we put these?
