Gammu is a project which encompasses applications, scripts and drivers for managing various functions on cellular phones and similiar devices.
It is a stable and mature codebase with support for many models available on the market and provides functions unavailable in other similiar projects. Long term development is oriented towards making a shared API for classes of device rather than supporting single phone models (which are eventually made obsolete with the arrival of new models).
This software was earlier (up to version 0.58) named MyGnokii2, current name Gammu is not connected with Gammu from "Heretics of Dune" written by Frank Herbert. We name this "main" project core too, because there are various other projects based on it available now.
