QOTW:  "But I like to [polish] the code while it does not yet exist, or
make hundreds of new options DURING the programming. That's why many of
my programs never see the daylight :)" -- Dino Levy

"For a long time, the industry labored under the illusion that if we
could all agree on One Big API then we'd have interoperability.
Examples have included Posix, X11, OLE/COM/DCOM, CORBA, DCE, OpenDoc,
and  the list goes on; and it's never, ever, ever worked (with the
single exception of the "sockets" library for IP networking)."  --
