NOTE 
As used in this book, the term commercial software developers means developers
who write and sell commercial software. Synonyms include "shrink-wrapped software
developers" and "independent software vendors" (ISVs). The term corporate
software developers includes both developers who write software for in-house
functions (such as inventory control) and developers who write software that is
part of or closely tied to the goods and services sold by a corporation (such as
the switching software used by telephone companies). In addition to corporations,
a variety of other organizations include software developers with similar
characteristics and concerns.
