+%description
+NBD — Network Block Device — is a protocol for accessing Block Devices
+(hard disks and disk-like things) over a Network.
+
+This is the NBD client library in userspace, a simple library for
+writing NBD clients.
+
+The key features are:
+
+ * Synchronous and asynchronous APIs, both for ease of use and for
+   writing non-blocking, multithreaded clients.
+
+ * High performance.
+
+ * Minimal dependencies for the basic library.
+
+ * Well-documented, stable API.
+
+ * Bindings in several programming languages.
+
