+    """Boost provides free peer-reviewed portable C++ source libraries. A large
+    part of Boost is provided as C++ template code which is resolved entirely
+    at compile-time without linking. This package aims to provide the most
+    useful subset of Boost libraries for template use among CRAN package. By
+    placing these libraries in this package, we offer a more efficient
+    distribution system for CRAN as replication of this code in the sources of
+    other packages is avoided. As of release 1.60.0-2, the following Boost
+    libraries are included: 'algorithm' 'any' 'bimap' 'bind' 'circular_buffer'
+    'concept' 'config' 'container' 'date'_'time' 'detail' 'dynamic_bitset'
+    'exception' 'filesystem' 'flyweight' 'foreach' 'functional' 'fusion'
+    'geometry' 'graph' 'heap' 'icl' 'integer' 'interprocess' 'intrusive' 'io'
+    'iostreams' 'iterator' 'math' 'move' 'mpl' 'multiprcecision' 'numeric'
+    'pending' 'phoenix' 'preprocessor' 'random' 'range' 'smart_ptr' 'spirit'
+    'tuple' 'type_trains' 'typeof' 'unordered' 'utility' 'uuid'."""
