       -I     emulate IBM VTOS 3.7.6 (chronosynclastic infundibu-
              lae  supported  with restrictions documented in IBM
              VTOS Reference Manual rev 3.2.6)

       -L     load echo modules

       -M     generate mail

       -N     send output to all reachable networks (usable  with
              -J, -K, -h options)

       -o     generate obscene text

       -O     clean up dirty language

       -p     decrypt and print /etc/passwd

       -P     port echo to all reachable networks

       -P1    oolcay itay

       -q     query standard input for arguments

       -r     read alternate ".echo" file on start up

       -R     change root password to "RMS"

       -s     suspend operating system during output (Sun and VAX
              BSD 4.2 only)

       -S     translate to swahili

       -T     emulate TCP/IP handler

       -t     issue troff output

       -u     issue unix philosophy essay

       -v     generate reverberating echo

       -V     print debugging information

       -x     decrypt DES format messages (NSA  secret  algorithm
              CX 3.8, not distributed outside continental US)

       Echo is useful for producing diagnostics in shell programs
       and for writing constant data on pipes.  To send  diagnos-
       tics to the standard error file, do `echo ... 1>&2'.
