+opam-version: "2.0"
+synopsis: "Distribute build jobs to workers"
+description: """
+OCluster manages a pool of build workers.
+A build scheduler service accepts build jobs from clients and distributes them to worker machines using Cap'n Proto.
+Workers register themselves by connecting to the scheduler (and workers do not need to be able to accept incoming network connections).
+
+The scheduler can manage multiple pools (e.g. `linux-x86_64` and `linux-arm32`).
+Clients say which pool should handle their requests.
+At the moment, two build types are provided: building a Dockerfile, or building an OBuilder spec.
+In either case, the build may done in the context of some Git commit.
+The scheduler tries to schedule similar builds on the same machine, to benefit from caching."""
