mediagoblin-init-scripts/installer.sh

#!/bin/sh
## DESCRIPTION
# This script will download the mediagoblin init scripts and install them for
# you.
# The script needs to know where your mediagoblin installation is. By default
# this will be sed to what `pwd` will output when you run this script.
#
# This script uses the Dependency Based Boot in Debian >= 6.0
# <http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot>
#
## USAGE
#
# # This will download the latest version of the installer.sh script directly
# # From gist.github.com (-L allowing a 302 redirect to raw.github.com), then
# # pipe the script directly through `sh` (presumably /bin/sh).
# $ curl -L http://wandborg.se/mediagoblin-init-scripts/installer.sh | sh
#
# By default the MG_ROOT will be set to `pwd` and the user will be set to the
# user you run the script as.
