Re: RDBMS backend

>From experience, the timeframe to an official release can be quite
indefinite :-)  I can zip up a set of files for you to try and call
this a pre-release that hopefully will evolve into a proper release
sometime down the road.  The main issue is that so far we don't
support dynamic loading of modules or STELLA systems outside of Lisp.
So, if you use the Java or C++ version of PowerLoom you'd have to edit
the top-level function to call the appropriate startup function as
well as (in C++) handle the linking of the additional libraries.

If you do want to use it in Lisp there is the additional issue of
database access support.  We've mainly tested this with Allegro using
its AODBC interface and with OpenMCL using CLSQL.  Conceivably, CLSQL
should also work with CMUCL (and maybe SBCL under Windows), but I
don't think we've ever tried that.

Anyway, we should take this offline into a private discussion and see 
what makes the most sense.
