'Fraid not, it blew my head in.  I think I need more paracetamol to
fight this viral infection -- programming Groovy isn't doing the job :-)

I guess I need to play with Ruby on Rails and Grails from scratch toi
see how this computational model works currently it just looks like
overly convoluted mixing of XML and Groovy.  My problem though.

I have a need of creating a small database / finance transaction related
Web site to try out a business idea.  It took me 3ns to reject PHP, the
job is not big enough for Java per se so I had decided to use Ruby on
Rails.  Perhaps I should use Grails?
