+Boost.Core
+==========
+
+Boost.Core, part of collection of the [Boost C++ Libraries](http://github.com/boostorg), is a collection of core utilities used by other Boost libraries.
+The criteria for inclusion is that the utility component be:
+
+* simple,
+* used by other Boost libraries, and
+* not dependent on any other Boost modules except Core itself, Config, Assert, Static Assert, or Predef.
