# This file can be used with `nixops` to create a virtual machine that has
# Termonad installed.
#
# I use this to test out Termonad in a desktop environment with a menubar.
#
# On my development machine, I use XMonad as a Window Manager, so there are
# no Window decorations for any X application.  This file creates a VM
# with Termonad installed in Gnome 3.  This lets you see what Termonad
# looks like when it has Window decorations, a title bar, etc.
#
# A virtual machine can be created based on this file with the following
# commands:
#
# $ nixops create --deployment termonad-test .nix-helpers/nixops.nix
# $ nixops deploy --deployment termonad-test
#
# This should open up a VirtualBox machine and start installing Gnome 3,
# Termonad, etc.
#
# You should be able to login with the username "myuser" and password "foobar".
#
# When you are done you can destroy the machine and delete the deployment:
#
# $ nixops destroy --deployment termonad-test
# $ nixops delete --deployment termonad-test
#
