# First ensure you have the necessary gems by cd'ing to this directory and
# running 'bundle install'. Then use as follows:
#
#   $ export GUARD_RELEASE_NAME=development # Default `development`
#   $ export GUARD_SYNC_USER=root # Default `root`
#   $ export GUARD_SYNC_HOST=192.168.124.10 # Default `192.168.124.10`
#   $ export GUARD_SYNC_PORT=22 # Default `22`
#   $ export GUARD_TREE_TARGET=/opt/crowbar # Default `/opt/crowbar`
#   $ export GUARD_MIRROR_TARGET=/root/barclamps # Default `/root/barclamps`
#   $ export GUARD_SCRIPT_TARGET=/opt/crowbar/bin # Default `/opt/crowbar/bin`
#   $ bundle exec guard
#
# Now all required files and directories are getting synchronized with the
# admin node so you can work with this crowbar files now. More about Guard
# at https://github.com/guard/guard#readme.
