# How to handle variable replacement - as of 1.2, Jinja2 variable syntax is
# preferred, but we still support the old $variable replacement too.

# try to do replacement on $variable style variables.
#
# legacy_playbook_variables=yes
# if you need to use jinja2 extensions, you can list them here
# use a coma to separate extensions, e.g. :
# jinja2_extensions=jinja2.ext.do,jinja2.ext.i18n
