%description
cliargs is a command-line argument parser for Lua. It supports several types of arguments:

  1. required arguments
  2. optional arguments with different notations: -short-key VALUE and/or --expanded-key=VALUE
  3. optional arguments with multiple-values that get appended to a list
  4. optional "flag" arguments (on/off options) with notations: -short-key and/or --expanded-key
  5. a single optional "splat" argument which can be repeated (must be the last argument)

Optional arguments can have default values (strings), flags always default to 'true'.
