This directory contains (what we consider) fundamental

classes required for any serious Smalltalk application

(both it headless or GUI-based).

Of course, for special applications, even this set of

classes could be reduced (for smaller apps, 

some of LargeInteger, FLoat, Fraction etc. could be left

out).

We do not provide tools or support for such minimal 

configurations - with modern, paged OperatingSystems, there

is also less sense in doing so, since unused code is simply

paged out or never paged in at all.
