Wader is a 3G communications software (GPL licensed), consisting of:

* wader-core: a fork of the core of Vodafone Mobile Connect Card driver for Linux, with some of its parts rewritten and improved to be able to interact via freedesktop's D-BUS with other applications of the Linux/OSX desktop. The core can be extended through plugins that allow it to support more devices and distros.
* wader-gtk: a simple user interface in GTK+, decoupled from core using D-BUS methods and signals.
* wader-doc: Wader API and documentation for how to add plugins, plus some examples of its API
