        `txt` - the inline groovy commands to execute

    - #### public Commandline.Argument createArg()

    - #### public Path createClasspath()

      Returns a new path element that can be configured. Gets called for instance by Ant when it encounters a nested <classpath> element.

      Returns:
        the resulting created path

    - #### protected void execGroovy(String txt, PrintStream out)

      Exec the statement.

      Parameters:
        `txt` - the groovy source to exec
        `out` - not used?

    - #### public void execute()

      Load the file and then execute it

    - #### public Path getClasspath()

      Gets the classpath.

      Returns:
        Returns a Path

    - #### public boolean getParameters()

      Returns true if parameter metadata generation has been enabled.

    - #### public static void main(String[] args)

    - #### protected void printResults(PrintStream out)

      print any results in the statement.

      Parameters:
        `out` - the output PrintStream to print to

    - #### protected void runStatements(Reader reader, PrintStream out)

      Read in lines and execute them.

      throws:
        java.io.IOException if something goes wrong
      Parameters:
        `reader` - the reader from which to get the groovy source to exec
        `out` - the outputstream to use

    - #### public void setAppend(boolean append)

      Whether output should be appended to or overwrite an existing file. Defaults to false.

      Parameters:
        `append` - set to true to append

    - #### public void setClasspath(Path classpath)

      Sets the classpath for loading.

      Parameters:
        `classpath` - The classpath to set

    - #### public void setClasspathRef(Reference ref)

      Set the classpath for loading using the classpath reference.

      Parameters:
