Here's the tree layouts:
{c++ namespaces}

-----------------------------------------------
Custom Package directories
{gov::sandia::ccaffeine}
dc/ (see below)
port/ (abstract ports expected by ccaffeine but not part of the CCA spec (yet))
cmd/
sc99/
util/
parameters/
jc++/	(c++ only)

{gov::doe::esi}
esi/

{org::gnu}
gnu/


-----------------------------------------------
ccaffeine core
{gov::sandia::ccaffeine::dc[::the-leaf-name]}
dc/
dc/component (?? migrates up a level? out of tree entirely?)
dc/framework (was dc_fwk)
dc/distributed
dc/port		(default implementations of ccaffeine port/ headers above)
mc/user_iface (MVC pattern, drivers)
dc/user_iface/ccacmd (specializations for us of the cmd package)
dc/user_iface/gui (java only)

The jeembo stuff migrates to viz-stv in the ccaffeine repository.
