Postal mail today brought me the latest issue of the IEEE Computing
Edge magazine, which presents short articles from other recent IEEE
publications.  In it, there is an article with numerous mentions of
Doug McIlroy, early Unix, software tools, and software modularization:

	Gerard J. Holzmann	
	Software Components
