+=head1 DESCRIPTION
+
+B<vsys> is a development tool to make AFS system calls from the command
+line. <I<call number>> is the AFS system call to be invoked. <I<parms>>+
+are the values to pass to the system call. Knowledge of the AFS system
+call layer is required to know valid call numbers and parameters.
+
+=head1 CAUTIONS
+
+B<vsys> is intended for debugging AFS at a low level and is therefore
+intended for AFS developers. System Administrators and AFS users should
+use the higher-level interfaces provided by L<fs(1)>, L<aklog(1)>,
+L<klog(1)>, and L<pagsh(1)> instead.
+
+B<vsys> provides a way to pass arbitrary data into the AFS system call
+mechanism. Caution should be taken when using or providing this binary on
+a system, as incorrect use as a privileged user could cause a system to
+panic, hang, or perform an unsafe operation.
+
