I was trying to figure out how Boost handles deprecated classes, 
functions, headers, macros, etc.

The following command finds several approaches within boost
$ grep -ir deprecate boost-1.44.0/include/boost/* \
  | grep -v "This header is deprecated" \
  | grep -v BOOST_SPIRIT_DEPRECATED

Surprisingly, none of these use compiler support.  e.g.
http://stackoverflow.com/questions/295120/c-mark-as-deprecated

Where can one find guidelines on how to deprecate things in Boost?  What 
is the proper way to check that code using Boost is clean?

Thanks,
Daniel
