Without going into all the details (I've been in the same lab as Dave 
Korn for many years), ksh and the other tools are part of a long 
process of tool development.  The tools co-evolved, with generic 
functions being split out from ksh and other tools and moved into a 
common library.  To give one example, sfio is a better I/O library (for 
many purposes) than stdio.  Naturally, ksh uses it, which in turn means 
that you can't build ksh without first building sfio.

For more details on the tools and their philosphies, see
http://www.research.att.com/resources/books/reuse (but I think that the 
book is out of print).
