usage="Usage: $0 [-p project] [-i] [-f file] variable|file|host|[group]

    -A host      Show all variable values for host (requires ansible-variables)
    -f file      Which vars file (which vars file to use, e.g. database_servers.yml)
                 Only required for files that do not reside inside
                 <project>/inventory/group_vars
    -p project   Name of the project to retrieve data from
    -i [group]   Inventory mode, show groups instead of variables,
                 if no group is supplied, 'all' is used
    -h           This text

When the input variable is a filename (NOTE: do not put in full paths!) the
script will render the contents of the file. If multiple files with the same name
exist, the script will prompt which one to use.

NOTE: This is different then using -f, as that is meant to select which vars file to read!
