+.TH OII 1df "June 2017" "Manual page for oii"
+\- run a command on input only if there's at least one byte of input
+CMD [ARGS ...] < file
+CMD [ARGS ...]
+Run the given program passing in stdin but only if at least one byte of input
+is actually received, rather like the -E switch to mail(1) behaves on
+bsd-mailx. If no input is received, exit silently with an error status.
+It's slow, and doesn't work as a pipe. The entire input is written to disk and
+then tested for filesize before being re-emitted. There's almost certainly a
+more efficient way to do this while still remaining byte-safe.
