+.SH NAME
+rdma_xclient \- RDMA CM communication client test program
+.SH SYNOPSIS
+.sp
+.nf
+\fIrdma_xclient\fR [-s server_address] [-p server_port] [-c comm_type]
+.fi
+.SH "DESCRIPTION"
+Uses synchronous librdmam calls to establish an RDMA connection between
+two nodes. This example is intended to provide a very simple coding
+example of how to use RDMA.
+.SH "OPTIONS"
+.TP
+\-s server_address
+Specifies the address of the system that the rdma_server is running on.
+By default, the client will attempt to connect to the server using
+127.0.0.1.
+.TP
+\-p server_port
+Specifies the port number that the server listens on. By default the server
+listens on port 7471.
+\-c communication type
+Specifies the type of communication established with the server program.
+'r' results in using a reliable-connected QP (the default). 'x' uses
+extended reliable-connected XRC QPs.
+.SH "NOTES"
+Basic usage is to start rdma_xserver, then connect to the server using the
+rdma_client program.
+.P
+Because this test maps RDMA resources to userspace, users must ensure
+that they have available system resources and permissions. See the
+libibverbs README file for additional details.
