11+-- | This module provides a 'Data.IntMap' variant which uses the value's
12+-- 'Monoid' instance to accumulate conflicting entries when merging
13+-- 'Map's.
14+--
15+-- While some functions mirroring those of 'Data.IntMap' are provided
16+-- here for convenience, more specialized needs will likely want to use
17+-- either the 'Newtype' or 'Wrapped' instances to manipulate the
18+-- underlying 'Map'.
