  # If there is a global {{$flarg}} variable which is an instance of some kind of driver, rename it to {{$flarg_driver}}
  # In {{lib/base.php}}, create a global {{$flarg}} which is an instance of {{Flarg::}}
  # For each static method in {{Flarg::}}
   # Find all calls of the method and replace {{Flarg::method()}} with {{$flarg->method()}}.  (**Possible exception:** if the method is truly static, meaning it will always produce the same output given the same parameters, you might want to keep it static.)
- # Remove {{@static}} in phpdoc comment
  # For each global variable ({{$flarg_driver}} is used as an example):
   # Add a {{getDriver()}} method to {{Flarg::}}
   # Make {{getDriver()}} return the global variable's value
- # FInd references to the global variable, and replace each with a call to {{$flarg->getDriver()}} (Note: With PHP4, you may need a temporary variable, since {{$flarg->getDriver()->foo()}} does not parse.)
+ # Find references to the global variable, and replace each with a call to {{$flarg->getDriver()}}
   # When all references are replaced, do **one** of the following:
    # Move initialization code for the value into the method
    # Introduce a field, move initialization code into constructor
    # Introduce a field which defaults to {{null}}, move initialization code into getter, but only execute when the field is {{null}} (Note, beware of introducing cycles.)
