75 NBD — Network Block Device — is a protocol for accessing Block Devices
76 (hard disks and disk-like things) over a Network. This is the NBD client
77 library in userspace, a simple library for writing NBD clients.
78
79 The key features are:
80 - Synchronous API for ease of use.
81 - Asynchronous API for writing non-blocking, multithreaded clients. You
82 can mix both APIs freely.
83 - High performance.
84 - Minimal dependencies for the basic library.
85 - Well-documented, stable API.
86 - Bindings in several programming languages.
87 - Shell (nbdsh) for command line and scripting.
