DESCRIPTION
       Rink is a unit conversion and calculation tool which can be used for
       both small and simple arithmetic and more complex dimensionality
       analysis and other tasks.

OPTIONS
       --config-path
           Prints a path to the config file, then exits.

       --fetch-currency: Fetches the latest version of the currency data, then
       exits. Can be used as part of a cron job, possibly together with
       setting currency.cache_expiration_enabled to false.

       -f, --file <file>
           Reads expressions from a file, one per line, printing them to
           stdout and then exitting.

       -h, --help
           Print help information and then exits.

       -V, --version
           Prints the current version and then exits.

EXIT STATUS
       Returns 0 unless an error prevented rink from starting up.

ENVIRONMENT
       NO_COLORS
           If set to a non-empty string, rink will disable colored text
           rendering.

FILES
       Rink looks for a configuration file in
       $XDG_CONFIG_DIR/rink/config.toml, see rink(5).

       Rink relies on some data files, which are found using a search path.
       See rink-defs(5) and rink-dates(5).

       Downloaded currency data is saved in $XDG_CACHE_DIR/rink/currency.json.
