BuildMonkey is an automated build, integration, and test platform for large-scale software development, particularly for distributed teams. It lets you manage multiple projects at once on different platforms and with different build technologies (Ant, make, gmake, etc.) and monitor SCM repositories to know what changed, when, and by whom. Build results are known immediately through email notification, and complete build logs are available via a central build dashboard. BuildMonkey integrates with the BuildMonkey EVT test suite to know the status of your host and network infrastructure at all times. Successful builds can be tagged in the SCM repository so they can be recreated.
RakNet is a networking API that is a wrapper for reliable UDP and higher level functionality on Windows, Linux, and Unix. It allows any application to communicate with other applications on the same computer, over a LAN, or over the internet. Although it could be used for any networked application, it was developed specifically for rapid development of online games and the addition of multiplayer to single player games.
