Can you really *expect* that someone running B20 for 5+ years can 
remember from "which package" to select so you will not lose a 
particular program that you've been using for years.  Heck I didn't even 
know it was part of the "linux" util package.  I never used a Linus 
system before.  The "cal" command was introduced back in SVR2 days 
(~1976)!  Way before Linux came on the scene!  Yes, I'm showing my age.
