  The Scala library that provides extension methods to Apache Commons CLI.

  How It Works

  Here's an example showing the library in action.

  import little.cli.Cli.{ application, option }
  import little.cli.Implicits._
  
  // Create application with supplied usage and options
  val app = application("grep [ options ... ] <pattern> [ <fileName> ... ]",
    option("i", "ignore-case", false, "Perform case insensitive matching"),
    option("l", "files-with-matches", false, "Print file name only"),
    option("m", "max-count", true, "Stop reading file after 'num' matches").argName("num"),
    option("n", "line-number", false, "Include line number of match"),
    option("r", "recursive", false, "Recursively search subdirectories"),
    option("x", "exclude", true, "Exclude filename pattern from search").argName("pattern")
  )
  
  val args = Array("-ilr", "--exclude", "*.swp", "exception", "src/main/scala")
  
  // Parse arguments
  val cmd = app.parse(args)
  
  cmd.hasOption("help") match {
    case true  =>
      // Print help to System.out
      app.printHelp()
    case false =>
      // Get command arguments and pretend to do something
      val pattern  = cmd.getArg(0)
      val fileName = cmd.getArg(1)
      println(s"Searching for files with '$pattern' in $fileName directory...")
  }
