Gecode is a toolkit for developing constraint-based systems and applications. Gecode provides a constraint solver with state-of-the-art performance while being modular and extensible.

This package contains the GenomeTools shared library and header files. It offers efficient sequence analysis components, available via an object-oriented interface.

Geomview is interactive geometry software which is particularly appropriate for mathematics research and education.

Gerris is a system for the solution of the partial differential equations describing fluid flow.

getdns is a modern asynchronous DNS API. It implements DNS entry points from a design developed and vetted by application developers, in an API specification edited by Paul Hoffman. This API intends to offer application developers a modernized and flexible way to access DNS security (DNSSEC) and other powerful new DNS features; a particular hope is to inspire application developers towards innovative security solutions in their applications.
