 Create a writable/readonly snapshot of the subvolume \fI<source>\fR with the
 name \fI<name>\fR in the \fI<dest>\fR directory.
 If only \fI<dest>\fR is given, the subvolume will be named the basename of \fI<source>\fR.
 If \fI<source>\fR is not a subvolume, \fBbtrfs\fR returns an error.
 If \fI-r\fR is given, the snapshot will be readonly.
+If \fI-R\fR is given, the snapshot will be made recursively. \fI-R\fR and
+\fI-r\fR cannot be used togheter. The -R switch requires the root capability.
