# Boost libraries detection and automatic build-up.

# Minimum required version of Boost and required components have to

# By "required components" we here mean compiled Boost libraries.

#
|

# #. cross-dependencies between required components are not checked for.

# For example, Boost.Timer depends on Boost.Chrono and Boost.System thus you

# should ask explicitly for all three

# #. the project admin has to make sure that ``BOOST_MINIMUM_REQUIRED`` and the

# ``fetch`` directive point to the same version of Boost
