I definitely appreciate everyone's work here, but not being a regular user 
of Ant or Middlegen, this is an uphill climb.  There have been two 
projects now where I've thought, "I'll try Middlegen w/ Hibernate", only 
to revert back to hand-coding the XML files.

(I think) all the pieces are there - couldn't this just be a big 
executable jar file with an adjacent folder to place jdbc drivers in?  
Download the jar, copy your JDBC drivers to the folder, double click, type 
in connection info or browse to a previously saved profile.  Man, would 
that make life easy.

Just thinking outloud...
