Nit sure what do you mean exactly here. What we could do is a
configure generating the rebar.config or if not possible directly via
a make macro.  My first idea was:

configure -> generate different mae files + config, make using rebar to compile

Do we really need a script for that ? Like I read it the script allows
us to easily move in svn the files. Why not at first move like the
original plan everything in its own folder (couchdb_core,
couchdb_htpp, ...) and then use the current make file mecanism ? After
that we could think to put in rebar.

Wjhat do you think ?
