It implements an asynchronous interface on stdin/stdout, with an ASCII driven command language. +<P> +<P> + +If stdin is a tty or if the <B>--prompt</B> option is given, then it issues a prompt to the user. Otherwise, it is silent, except for results. +<P> +<P> + +The program will accept multiple queries concurrently, with each result being marked with the ID provided on the output. The IDs are strings. +<P> +<P> + +If the <B>--serial</B> option is given, then the program will not attempt to execute concurrent queries, but will serialize all input and output. +<P> +<A NAME="lbAE"> </A> +<H2>QUERY LANGUAGE</H2> + +<P> +<P> + +There are eleven command that the program understands.
