In order to help myself sort through the various options when
faced with implementing a V3 command I have written up this page:
http://wiki.glassfish.java.net/Wiki.jsp?page=V3CLILandscape
The point of the document is to just get people started
in the right direction -- not to explain everything in
detail. Feel free to send me corrections and other feedback
as well as pointers to any additional documents I can refer
to.
Thanks,
Joe
