 NSPR 2.0 must implement its function across a range of platforms 
 including: MAC, Windows/16, Windows/95, Windows/NT, and several
 variants of Unix. Each implementation shares common code as well 
 as having platform dependent portions. This standard describes how
 the model dependent portions are to be implemented.
