HOWTO

# HAL
# ===
# This covers installation of PolicyKit and HAL

# PolicyKit
# =========
# PolicyKit is a prerequisite, but AFAIK, it's only available by grabbing
# it with git.  git is a tool that Linus T. came up with for Linux kernel
# development.  If you don't have git and don't want to get git, you can
# pass --disable-policy-kit to HAL's configure.

# Prerequisites:
# gawk
# grep
# sed
# pkg-config
# Glib
# D-Bus with Glib bindings
# xmlto
# PAM (if you don't have PAM, then skip PolicyKit)

kill `cat /var/run/hald/pid`
