	This really needs to be clearer in the FAQ to avoid more people
	to be "lured into" using the tds_ functions directly. I've been
	on the mailing list for four days and already I've seen
	discussions about changing the tds_login() dramatically. ;-)

	Excellent! Although I (as an absolute beginner on this) think
	programmers should be more directed towards using dblib and
	ctlib with good documentation (and a gentle push).

	We have earlier tried various ODBC drivers, both with MySQL and other
	RDBMS, but alas, the extra configuration and drop in efficiency really
	made us want to use fast, native connections to databases using
	libraries like libmysql and libtds.
