+    (description
+     "OpenFabrics Interfaces (OFI) is a framework focused on exporting fabric
+communication services to applications.  OFI is best described as a collection
+of libraries and applications used to export fabric services.  The key
+components of OFI are: application interfaces, provider libraries, kernel
+services, daemons, and test applications.
+
+Libfabric is a core component of OFI.  It is the library that defines and
+exports the user-space API of OFI, and is typically the only software that
+applications deal with directly.  It works in conjunction with provider
+libraries, which are often integrated directly into libfabric.")
