# usage: add the following hook to the oxidized config file:
#
# hooks:
# email_output:
# type: exec
# events: [post_store, node_fail]
# cmd: 'update-local-repo.sh ~/gitdir/ | mail -s "Oxidized updates for ${OX_NODE_NAME}" update-recipient@example.com'
# async: true
# timeout: 120
#
#
# The script takes a single argument, namely a git working directory name,
# e.g. "~/gitdir/". This is only used as a staging directory and should
# not be set to be the same as the git repo directory.
