Grand Unified Builder (GUB) is a mini source-based distribution and packaging system. It cross-compiles several packages with their dependencies and assembles them into a single installation package. It currently supports GNU/Linux, FreeBSD, Mac OS X, and Microsoft Windows installation packages. All packages are fully relocatable and can be installed with user privileges. Plain Python classes are used to describe package build specifics. For reasonably well behaved packages, individual build specifications can stay very simple by extending the generic build specification classes. It was originally developed for turnkey building of all LilyPond binary installers.
Grapple is designed to be a simple network layer, allowing the addition of multiuser features to an application for as little as a dozen lines of code. However, it also allows for more. It features simple client-server networking that keeps all clients aware of all other clients, passworded servers, and data transfer via TCP, UDP, or reliable UDP. Advanced features include network messaging via push, pull, or a combination, multiple methods of querying users, user groups for client bandwidth saving, network load reacting data transmission and retransmission, background pinging to monitor network states, server failover, and a fully functional lobby system.
