/**
* ({@code @wurblet}) Generates the remote delegate invocation code.
*
* In order for this wurblet to work, the method must be annotated with @RemoteMethod.
*
* usage:
* @wurblet <tag> RemoteMethod [--this] [--nocontext] [--instance=<object>]
*
* arguments:
*
* - --this: add the PDO itself to the method parameters.
* - --nocontext: don't pass the DomainContext.
* - --instance=<object>: object to invoke the method on in the remote implementation.
*
* For more options, see {@link DbModelWurblet}.
