This application was designed to meet the following requirements: <li> <ul>A process can register itself using any term.</ul> <ul>A process can register more than one name</ul> <ul>A process can publish non-unique {Key,Value} 'properties' </ul> <ul>The registry must be efficiently searchable</ul> </li> As additional features, the registry was designed to allow global registration, and a special {Key,Value} property called a counter. It is also possible to create an 'aggregate counter', which will continuously reflect the sum of all counters with the same name. <em>In its current state, the global registration facility is broken and should not be used. It will be migrated over to a new version of gen_leader. This work will be done with low priority unless people express a strong urge to use this functionality.</em> @end
