An helper to avoid keeping ansible.cfg in playbook repos.

From this repo

• make install will install ansible-cfg.mk, ansible-cfg.jsonnet and ansible-cfg.yml in /usr/local/bin

From any pristine ansible playbook repo

• ansible-cfg.mk $config will invoke ansible-cfg.jsonnet to create various ansible configs in ansible-cfg and link ansible.cfg to $config (default to full)

• ansible-cfg.yml -e dir=$(pwd) will create local dirs needed by ansible config and populate .gitignore and/or .git/info/exclude

• ansible-cfg.mk exclude is a shorthand for ansible-cfg.yml -e dir=$(pwd)

• ansible-cfg is a shorthand for ansible-cfg.mk
