+                  Supplying passwords to rtty
+
+If compiled with -DSSHPASS, rtty will run sshpass(1) with the -e
+flag, expecting a password to be set in the SSHPASS environment
+variable.
+
+If you often need to log into remote servers without public key
+authentication, consider compiling a special version of rtty -- I
+suggest the name rttyp -- and installing it alongside the normal
+version of rtty.
