To write a pretty printer that completely syntax checks C is horribly
wasteful.  Only certain constructs cause indentation and that is all thea
a pretty printer should recognize.  This is important because a pretty printer
is an excellent debug tool when the C parser doesn't help. (i.e. where did
I leave out that } ).  The last pretty printer I wrote took 4 hours and
only recognized { } for while if repeat and a few others.

Forget Yacc.  The source for yacc would be MUCH more complicated than a 
simple scanner required for prettyPrint.

(I know, flame away.  I just think that Yacc has it's place and its not
 for every job)
