Longer worked examples in the findutils documentation - comments?

[James Youngman]

The Findutils documentation (in the development CVS tree) now includes
two longer worked examples which include several possible approaches
to solving some common problems with a discussion of why some ways of
solving the problem are better than others.

I'd be glad of some feedback on these examples: are they useful of
themselves?  Are there other good ideas for useful examples which
offer an opportuinity to cover things that people should know about
using findutils? 

Please note that I haven't actually checked the examples in the
timestamps section.  I'm hoping to do it at some stage this weekend,
but I'm not completely sure I'll have time.

Regards,
James.
