+Echoes its input.  By default, this prints in a Lisp-friendly fashion
+(so that the value is useful to a Lisp command using the result of
+@command{echo} as an argument).  If a single argument is passed,
+@command{echo} prints that; if multiple arguments are passed, it
+prints a list of all the arguments; otherwise, it prints the empty
+string.
