.TP 8
+.B \-filename \fIfile\fP
+Instead of reading from memory, read from the given file until EOF, then
+re-open it. If you have permission, /dev/mem is an interesting choice here.
+(Note that /dev/null won't ever display anything, because it returns EOF
+without ever returning any data.)
+.TP 8
.B \-delay \fImicroseconds\fP
How much of a delay should be introduced between steps of the animation.
-Default 100000, or about 1/10th second.
+Default 10000.
