 OBus is a pure OCaml implementation of D-Bus. It aims to provide a
 clean and easy way for OCaml programmers to access and provide D-Bus
 services.
 .
 D-Bus is a message bus, used for sending messages between
 applications. It supports broadcast messages, asynchronous messages
 (thus decreasing latency), authentication, and more. It is designed
 to be low-overhead. D-Bus also supports a method call mapping for its
 messages.
 .
 This package contains development files of OBus.
