+Keystrokes are read from standard input. Normally this is the user's
+terminal, but pipes and redirection also work. This allows for things
+like:
+.PP
+echo emq | fbv --noinfo --noclear image.jpg
+.PP
+ ...which will display image.jpg (enlarged and rotated 90 degrees), then exit, leaving
+the image visible. The "q" in the echo command is actually redundant, as
+fbv will exit on stdin EOF.
