The MRG Import Tool (MRG importer) ensures that the scope within which it is run, obtains a local copy of all MRGs that are available in the scopes that are mentioned in the scopes section of its SAF. This makes life easy for various tools, e.g., the MRGT and the TRRT, that can now assume that all MRGs that they may need to consult in order to do their job, are readily available.
Please refer to the MRG Import Tool specifications for more information.
