+%description
+A newtype over 'Bool' with a better 'Vector' instance: 8x less memory, up to
+3500x faster.
+
+The <https://hackage.haskell.org/package/vector vector> package represents
+unboxed arrays of 'Bool's spending 1 byte (8 bits) per boolean. This library
+provides a newtype wrapper 'Bit' and a custom instance of an unboxed 'Vector',
+which packs bits densely, achieving an __8x smaller memory footprint.__ The
+performance stays mostly the same; the most significant degradation happens for
+random writes (up to 10% slower). On the other hand, for certain bulk bit
+operations 'Vector' 'Bit' is up to 3500x faster than 'Vector' 'Bool'.
+
+=== Thread safety
+
+* "Data.Bit" is faster, but writes and flips are not thread-safe. This is
+because naive updates are not atomic: they read the whole word from memory,
+then modify a bit, then write the whole word back. Concurrently modifying
+non-intersecting slices of the same underlying array may also lead to
+unexpected results, since they can share a word in memory. *
+"Data.Bit.ThreadSafe" is slower (usually 10-20%), but writes and flips are
+thread-safe. Additionally, concurrently modifying non-intersecting slices of
+the same underlying array works as expected. However, operations that affect
+multiple elements are not guaranteed to be atomic.
+
+=== Similar packages
+
+* <https://hackage.haskell.org/package/bv bv> and
+<https://hackage.haskell.org/package/bv-little bv-little> do not offer mutable
+vectors.
+
+* <https://hackage.haskell.org/package/array array> is memory-efficient for
+'Bool', but lacks a handy 'Vector' interface and is not thread-safe.
