I also thought the strength of a system resided in its simplicity
(the old KISS principle) ...the underlying philosophy of UNIX -
small unitized modules which could be combined to perform useful
work.   Doesn't a large multipurpose application run against this
grain.

If you accept Beizer's hypothesis of one residual flaw per one hundred lines of 
tested source code then a very large multipurpose application has more 
chance of containing more bugs a small simple single purpose application.

Right?
