rapidj starts at $400US and does one thing only. Graffle starts at  
$80, might already be on your powerbook or powermac, and makes  
beautiful diagrams and charts of any kind. It is what visio wishes it  
could be.

Hrm... Probably 3 hours or so for the applescript. About an hour or  
two for the ruby.

The SQL generator is approximately 140 lines of applescript.
The model generator is approximately 130 lines of ruby.
The movie is approximately 3 meg. :)

> *) what do they do in the end?

Generate SQL and the relationship fields in the model. The model  
generator also: runs your rails command (no biggie); modifies your  
database.yaml to connect to postgresql (because WHO in their right  
mind would use mysql, really?), changes the username and db names so  
it will immediately connect; tells you what commands you might like  
to run to get bootstrapped; and then finally generates the model.
