weblogger.el implements MetaWeblog, Blogger and (hopefully soon) the Atom API weblogging APIs.
If you use ELPA (http://tromey.com/elpa), you can install via the M-x package-list-packages interface. This is preferrable as you will have access to updates automatically.
Otherwise, just make sure this file and xml-rpc.el are in your load-path (usually ~/.emacs.d is included) and put (require 'weblogger) in your ~/.emacs or ~/.emacs.d/init.el file.
