Function	`generate_dynamic`	Dymamically generate message classes from msg_cat .msg text gendeps dump.
Function	`_gen_dyn_modify_references`	Modify the generated code to rewrite names such that the code can safely co-exist with messages of the same name.
Function	`_gen_dyn_name`	Modify pkg/base_type name so that it can safely co-exist with statically generated files.
Function	`_generate_dynamic_specs`	Dynamically generate message specificition.

def generate_dynamic(core_type, msg_cat): ¶

@rtype: str

Returns
name to use for pkg/base_type for dynamically generated message class.

def _generate_dynamic_specs(msg_context, specs, dep_msg): ¶
