# Aegir quick install script
#
# This script is just a wrapper to the hostmaster-install command, which
# is part of the provision module. It is designed to be quickly
# downloaded and ran as the Aegir user (created as per the INSTALL.txt)
# and bootstrap aegir by downloading drush and provision.
#
# The real work happens in PHP, within the hostmaster-install command.
#
# It should keep to strict POSIX shell syntax to ensure maximum
# portability. The aim here is to ease the burden allow people using
# various platforms to zip through the install quicker.
#
# This script also *DOES NOT CHECK* if the requirements specified in
# INSTALL.txt have been met.  It's up to the admin to follow the proper
# install instructions or use the packages provided by their platform.
########################################################################
# This script takes the following steps:
#
# 1. downloads drush in $AEGIR_HOME
# 2. downloads provision in $AEGIR_HOME/.drush
# 3. delegate the rest of the install to hostmaster-install
