Debusine manages scheduling and distribution of Debian-related tasks to a distributed network of machines.
It is under active development by Freexian with the intention of providing easy access to a range of packaging tools and distribution-wide experiments.
If it's your first time exploring Debusine, you can start from What is Debusine for an introduction, or browse the index to the whole Debusine documentation. You may want to set up debusine-client if you have not already done so.
