deprecated:
  removed_in: 9.0.0
  why: the endpoints this module relies on do not exist any more and do not resolve to IPs in DNS.
  alternative: no known alternative at this point

module: webfaction_site
short_description: Add or remove a website on a Webfaction host
description:
    - Add or remove a website on a Webfaction host.  Further documentation at https://github.com/quentinsf/ansible-webfaction.
author: Quentin Stafford-Fraser (@quentinsf)
notes:
    - Sadly, you I(do) need to know your webfaction hostname for the C(host) parameter.  But at least, unlike the API, you do not need to know the IP
      address. You can use a DNS name.
    - If a site of the same name exists in the account but on a different host, the operation will exit.
    - >
      You can run playbooks that use this on a local machine, or on a Webfaction host, or elsewhere, since the scripts use the remote webfaction API.
      The location is not important. However, running them on multiple hosts I(simultaneously) is best avoided. If you do not specify C(localhost) as
      your host, you may want to add C(serial=1) to the plays.
    - See L(the webfaction API, https://docs.webfaction.com/xmlrpc-api/) for more info.
