Brian Coca d0c6d2ff1c poreted log_plays, syslog_json and osx_say callbacks to v2
renamed plugins to contrib (they are not really plugins)

# Dynamic inventory script which lets you use aliases from ~/.ssh/config.
#
# It prints inventory based on parsed ~/.ssh/config. You can refer to hosts
# with their alias, rather than with the IP or hostname. It takes advantage
# of the ansible_ssh_{host,port,user,private_key_file}.
#
# If you have in your .ssh/config:
# Host git
# HostName git.domain.org
# User tkarasek
# IdentityFile /home/tomk/keys/thekey
#
# You can do
# $ ansible git -m ping
#
# Example invocation:
# ssh_config.py --list
# ssh_config.py --host <alias>
