Basic Object System
(BOS) A {C}-callable library that implements the
notion of {object} and which uses {Tcl} as its {interpreter}
for interpreted {methods} (you can have "compiled" methods in
C, and mix compiled and interpreted methods in the same
object, plus lots more). You can subclass and mix in existing
objects using BOS to extend, among other things, the set of
{tk} {widgets}. BOS is a {class}-free object system, also
called a prototype-based object system; it is modelled loosely
on the {Self} system from {Stanford University}.
