      StringMacroConverter filter =
          StringMacroConverter.getConverter(MacroConverter.MAKE_CONVERTER);
      String orig = "Your OS is $(os.name), running on an $(os.arch) cpu.";
      String news = filter.expandString(orig, System.getProperties());
      System.out.println(news);
    }

File usage:

    public void FileTest1() throws Exception
    {
      FileMacroConverter filter =
        FileMacroConverter.getConverter(MacroConverter.AT_CONVERTER);

      File sourceFile = new File("C:\\src.txt");
      String text = "Your OS is @os.name@, running on an @os.arch@ cpu.";
      createTempFile(sourceFile, text);

      if (destFile.exists())
      {
        destFile.delete();
      }
