Convert your Anvil (PC) worlds to PMAnvil (PMMP) worlds!
Put AnvilToRegion.jar and AnvilConverter.jar on your server's main folder. Install plugin and restart the server. Type /convert.
You must install Java in your server. For Centos, type "yum install java"
Thanks @ImagicalCorp for convert Anvil to MCRegion and thanks @Awzaw for convert MCRegion to PMAnvil.
