## 2 Requirements

Newsticker can be used with GNU Emacs version 21.1 or later as well as XEmacs. It requires an XML-parser (`xml.el`) which is part of GNU Emacs. If you are using XEmacs you want to get the `net-utils` package which contains `xml.el` for XEmacs.

Newsticker retrieves headlines either via Emacs' built-in retrieval functions, by an arbitrary external program that retrieves files via http and prints them to stdout (like wget, or – on a per feed basis – via an arbitrary Lisp command.
