openpandora-setup.sh

#!/bin/bash

# Shamelesly 'borrowed' from the mainline Angstrom setup-scripts
#   http://gitorious.org/angstrom/angstrom-setup-scripts/
# and modified to just support the needs for the OpenPandora stock
# firmware and build setup. If you want a more generic Angstrom
# setup please use the mainline scripts.

# Original script done by Don Darling
# Later changes by Koen Kooi and Brijesh Singh
# Hacked about for the OpenPandora by John Willis
