/** A Migration service.
* <br />
* The goal of migration is usually to replace old properties or data files
* with a new set, located elsewhere. The fact is that depending on where
* the data needs to be updated, the migration may need to be done at
* different places during jEdit's startup. <br />
* There is no specific time that all migration services are called currently.
* The service and interface exists primarily so you don't need to add a compilation
* dependency of the org.gjt.sp.jEdit class to your MigrationService class. <br />
* <br />
* Concrete instances need to guarantee that the migration itself is only done
* once.
* @see org.jedit.migration.OneTimeMigrationService
