Interface: org.sonatype.nexus.plugins.NexusPlugin
This extension component is meant to be used in Nexus plugins only. If it is found in a plugin, it will be invoked during install/uninstall/init phases of a plugin installation/uninstallation/initialization. Typical usage would be a need to perform some specific tasks on plugin install (i.e. it uses native code to do some magic and those needs to be copied somewhere, register them with OS, etc).
