Description:

Libxseg is a shared memory communication library. It is designed to
provide fast inter-process communication between distinct processes.
It is based on shared memory areas (segments) that each process (peer)
can map on its own address space. It lays down endpoints (ports),
messages (requests), and buffers over the shared segment. It also
specifies an API to interact with the segment and pass messages
between peers.

Its primary use is to support Archipelago's modular architecture and
provide low-latency message passing between different Archipelago
peers.
