|=======================================================================
+The `-l` option is a developer convenience for experimenting with a line-driven
+script, in the same spirit as `groovysh` but reading from a socket instead of a
+terminal. It is not an application server.
+
+It runs the given script once for every line a client sends, with the
+line available as the implicit `line` variable and the connection as `out` and
+`socket`. The listening socket is bound to the loopback address, so only
clients on
+the same machine can connect. Supply a host to listen more widely
> Provide a GroovySocketServer constructor variant with an address
