##
## Version 0.1 2014-05-07
## Trent Lloyd <trentl@webinabox.net.au>

## (1) Create a new directory, e.g. 'template-builder'
## (2) Download this file and name it Makefile
## (3) Make template/ directory, copy fstab.xen from an existing Ubuntu template (e.g. 12.04)
## (4) Create template/resolv.conf with your nameservers
## (5) Ensure you are running OnApp 3.1 (this assumes using /onapp/backups/templaets unpacking from OnApp 3.1)
## (6) You must run this script on a backup server with access to templates and backups
## (7) run 'make'
