#ISSUES:
# * find_includes should be called only once!
# * support mandatory
######## boost update ###########
## ITA: * the method get_boost_version_number does work
## * the rest of the code has not really been tried
# * make certain a demo is provided (in demos/adv for example)
# TODO: bad and underdocumented code -> boost.py will be removed in waf 1.6 to be rewritten later
