--   
--   Various data structures and custom data types to describe the

--   The implementation of the BWT relies upon <a>Seq</a> provided by the
--   <a>containers</a>.
--   
--   The internal <a>BWTMatrix</a> data type relies upon the <a>massiv</a>
--   package.

-- | <h1>Burrows-Wheeler Transform (BWT)</h1>
--   
--   The two functions that most users will utilize are <a>toBWT</a> and

--   <tt><a>Data.BWT.Internal</a></tt>.
--   
--   The helper functions for ByteString, <a>bytestringToBWT</a>,
--   <a>bytestringFromWord8BWT</a> , <a>bytestringFromByteStringBWT</a> and
--   Text, <a>textToBWT</a> and <a>textFromBWT</a> should help for common
--   use cases.
--   
--   <tt><a>Data.BWT.Internal</a></tt> also has the function
--   <a>createBWTMatrix</a>, which can be useful as well, although not used
--   by either <a>toBWT</a> or <a>fromBWT</a>.
