	* ditty.c: Added "-h" option to display usage, which will also
	be displayed, on stderr, if an unknown option is encountered.
	Note that "unknown option" doesn't include -k or -d when support
	for one of those options is compiled out - they are silently
	ignored.  Also added legal disclaimer at top of file.

	* ditty.1: mentioned certain options which could be disabled
	depending on compile-time options.

	* ditty.c (main): Set ditty to default to consoundInit as the
	initialization function, unless support is not compiled in, in
	which case ditty will default to devdspInit.

	* Added configure script and associated files. ditty can now be
	compiled without support for one or the other sound output methods.
