#
# ansible-pull is a script that runs ansible in local mode
# after checking out a playbooks directory from source repo.  There is an
# example playbook to bootstrap this script in the examples/ dir which
# installs ansible and sets it up to run on cron.

# usage:
#   ansible-pull -d /var/lib/ansible \
#                -U http://example.net/content.git [-C production] \
#                [path/playbook.yml]
#
# the -d and -U arguments are required; the -C argument is optional.
#
# ansible-pull accepts an optional argument to specify a playbook
# location underneath the workdir and then searches the source repo
# for playbooks in the following order, stopping at the first match:
#
# 1. $workdir/path/playbook.yml, if specified
# 2. $workdir/$fqdn.yml
# 3. $workdir/$hostname.yml
# 4. $workdir/local.yml
#
# the source repo must contain at least one of these playbooks.
