Acquire Method
+ This is a skeleton class that implements most of the functionality
+ of a method and some useful functions to make method implementation
+ simpler. The methods all derive this and specialize it. The most
+ complex implementation is the http method which needs to provide
+ pipelining, it runs the message engine at the same time it is
+ downloading files..
