#
# PLEASE READ THIS:
# Probably you will never have to update I2P packages with upgradepkg,
# just because I2P has an auto-update function.
# Really you should not ever use any "upgrade" method.
#
# The correct way to upgrade is to: 
# 1: install the upgrade
# 2: remove the old package
#
# It is a terrible shame that upgradepkg doesn't do this, infact, 
# it would actually be the correct way for *any* package!
