# Heavily based on the Slackware 12.1 SlackBuild
# Slackware build script for i2p

# PLEASE READ THIS:
# Probably you will never have to update i2p packages with upgradepkg,
# just because i2p have an auto-update function.
# How to start i2p:
# After installpkg command, doinst.sh will execute a postinstallation script
# needed by i2p. After that you have to chmod +x /etc/rc.d/rc.i2p and start
# i2p service with /etc/rc.d/rc.i2p start.
# Now tell your browser to user this proxy: localhost on port 4444 and open
# this page: http://localhost:7657/index.jsp
# Here you can configure i2p, watch network status and navigate anonimously.
# It's suggested to subscribe to various dns host, like i2host.i2p
# For any additional information, visit i2host.i2p and forum.i2p

#
# This mess is here due to the totally moronic way i2p does versioning.
# We correct it here.
