## Spawn Plugin

Allows in-game operators to easily spawn creatures at current location.

### Usage

    /jsp spawn cow
    /jsp spawn sheep
    /jsp spawn wolf

This command supports TAB completion so to see a list of possible
entitities, type `/jsp spawn ' at the in-game command prompt, then
press TAB. Visit
<http://jd.bukkit.org/beta/apidocs/org/bukkit/entity/EntityType.html>
for a list of possible entities (creatures) which can be spawned.
