XML/Upgrade

An upgrade is a "producible" type that a unit may produce to bring about changes in other units or pave the way for other units or upgrade to be produced. An upgrade may alter many stats of one or more unit types. (Note: This covers the Glest 3.1.2 specification. For GAE-specific extensions, see GAE/Upgrade_XML.)
