{{"To scaffold out your application, use:"|bold}}
$ bee hprose [appname] [-tables=""] [-driver=mysql] [-conn=root:@tcp(127.0.0.1:3306)/test]
If 'conn' is empty, the command will generate a sample application. Otherwise the command
will connect to your database and generate models based on the existing tables.
The command 'hprose' creates a folder named [appname] with the following structure:
