[e-lang] Joe-E 2.0 Release

[Tyler Close]

If I have multiple Eclipse projects that should be Joe-E verified and
where some are dependencies of others; how do I set up the new taming
infrastructure so that the Joe-E verifier does not complain about
types in one Joe-E verified project being used in a separate Joe-E
verified project? For example, currently I am getting Joe-E errors for
the web_send project, which depends on the ref_send project of the
Waterken server. How do I make these go away? When the Joe-E verifier
runs on the ref_send project, it spits safej files into
ref_send/taming; as well as dropping a Policy.java at
ref_send/src/org/joe_e/taming/Policy.java. My Joe-E preferences page
points at joe_e/taming where the safej files from the Joe-E
distribution reside. The Joe-E verifier does similarly for the
web_send project, spewing files into the web_send project directory.

Getting up and running with the new taming infrastructure in the Joe-E
verifier has been a trial for me. This business of generating taming
files for Joe-E verified code seems like a poor design to me.
