Learning bind is sort of like learning sendmail though.  They both do a million 
things you'll never need (and if you do you should probably change your 
design...).  The trick - especially when you start with the full references - is 
to figure out the simple part you need to understand and ignore the rest.  And 
when using distribution-packaged versions, most of what you need is already there.
