+ (description
+ "This package provides a fast implementation of a key-value store.
+Environments are commonly used as key-value stores, but every time a new key
+is used, it is added to R's global symbol table, causing a small amount of
+memory leakage. This can be problematic in cases where many different keys
+are used. Fastmap avoids this memory leak issue by implementing the map using
+data structures in C++.")
