There is only one flag added: `noJSON`. If this flag is set to true (i.e. `enumer -type=Pill -noJSON`), There are two flags added: `noJSON` and `sql`. If the noJSON flag is set to true (i.e. `enumer -type=Pill -noJSON`),
the JSON related methods won't be generated. the JSON related methods won't be generated. And if the sql flag is set to true, the Scanner and Valuer interface will
be implemented to seamlessly use the enum in a database model.
## Additional functions of this fork
