+Usage: ${0##*/} [[-e|-r] command [args...]]
+
+StumpIsh is the StumpWM shell. Use it to interact a running StumpWM
+instance.  When run from a terminal with no arguments, stumpish
+accepts commands interactively and prints each result.  If standard
+input is a pipe, stumpish executes any number of commands and prints
+the concatenated results. If the '-e' option and one argument are
+given on the command line, stumpish reads any number of lines from
+standard input and uses them as the argument to the named command.
+Otherwise, if one or more arguments are provided on the command line,
+the first is considered the name of the command to execute and the
+remainder is concatenated to form the argument.
+
+Example:
+	echo '(group-windows (current-group))' | ${0##*/} -e eval
+EOF
