# Usage $0 <arguments>
#
# Wrapper around nanobsd.sh with autodetection of already processed steps to
# provide some failsafe net, which avoids building world and/or kernel by
# default.
#
# Rick van der Zwet <rick@wirelessleiden.nl>
#
# Arguments:
# build                         - Build NanoBSD parts which are not build yet
# build force kernel            - Build NanoBSD and force rebuilding the kernel
# build force world             - Build NanoBSD and force rebuilding world
# edit                          - Manually edit the image
# config [for <node>]           - Configure image to be used for <node>
# rebuild                       - Rebuild NanoBSD (aka force rebuilding all)
# deploy on <node> [and reboot] - Deploy the image on node and reboot if needed
# ports update                  - Update the packages from ports 
# ports force rebuild           - Forcefully rebuilding all required packages
