+
+-- $parsec
+--
+-- Compared to Parsec 3, attoparsec makes several tradeoffs.  It is
+-- not intended for, or ideal for, all possible uses.
+--
+-- * While attoparsec can consume input incrementally, Parsec cannot.
+--   Incremental input is a huge deal for efficient and secure network
+--   and system programming, since it gives much more control to users
+--   of the library over matters such as resource usage and the I/O
+--   model to use.
+--
+-- * Much of the performance advantage of attoparsec is gained via
+--   high-performance parsers such as 'I.takeWhile' and 'I.string'.
+--   If you use complicated combinators that return lists of bytes or
+--   characters, there is less performance difference between the two
+--   libraries.
+--
+-- * Unlike Parsec 3, attoparsec does not support being used as a
+--   monad transformer.
+--
+-- * attoparsec is specialised to deal only with strict 'B.ByteString'
+--   input.  Efficiency concerns rule out both lists and lazy
+--   bytestrings.  The usual use for lazy bytestrings would be to
+--   allow consumption of very large input without a large footprint.
+--   For this need, attoparsec's incremental input provides an
+--   excellent substitute, with much more control over when input
+--   takes place.  If you must use lazy bytestrings, see the
+--   "Data.Attoparsec.ByteString.Lazy" module, which feeds lazy chunks
+--   to a regular parser.
+--
+-- * Parsec parsers can produce more helpful error messages than
+--   attoparsec parsers.  This is a matter of focus: attoparsec avoids
+--   the extra book-keeping in favour of higher performance.
+
+-- $incremental
+--
+-- attoparsec supports incremental input, meaning that you can feed it
+-- a bytestring that represents only part of the expected total amount
+-- of data to parse. If your parser reaches the end of a fragment of
+-- input and could consume more input, it will suspend parsing and
+-- return a 'T.Partial' continuation.
+--
+-- Supplying the 'T.Partial' continuation with a bytestring will
+-- resume parsing at the point where it was suspended, with the
+-- bytestring you supplied used as new input at the end of the
+-- existing input. You must be prepared for the result of the resumed
+-- parse to be another 'T.Partial' continuation.
+--
+-- To indicate that you have no more input, supply the 'T.Partial'
+-- continuation with an empty bytestring.
+--
+-- Remember that some parsing combinators will not return a result
+-- until they reach the end of input.  They may thus cause 'T.Partial'
+-- results to be returned.
+--
+-- If you do not need support for incremental input, consider using
+-- the 'I.parseOnly' function to run your parser.  It will never
+-- prompt for more input.
+--
+-- /Note/: incremental input does /not/ imply that attoparsec will
+-- release portions of its internal state for garbage collection as it
+-- proceeds.  Its internal representation is equivalent to a single
+-- 'ByteString': if you feed incremental input to a parser, it will
+-- require memory proportional to the amount of input you supply.
+-- (This is necessary to support arbitrary backtracking.)
+
+-- $performance
+--
+-- If you write an attoparsec-based parser carefully, it can be
+-- realistic to expect it to perform similarly to a hand-rolled C
+-- parser (measuring megabytes parsed per second).
+--
+-- To actually achieve high performance, there are a few guidelines
+-- that it is useful to follow.
+--
+-- Use the 'B.ByteString'-oriented parsers whenever possible,
+-- e.g. 'I.takeWhile1' instead of 'many1' 'I.anyWord8'.  There is
+-- about a factor of 100 difference in performance between the two
+-- kinds of parser.
+--
+-- For very simple byte-testing predicates, write them by hand instead
+-- of using 'I.inClass' or 'I.notInClass'.  For instance, both of
+-- these predicates test for an end-of-line byte, but the first is
+-- much faster than the second:
+--
+-- >endOfLine_fast w = w == 13 || w == 10
+-- >endOfLine_slow   = inClass "\r\n"
+--
+-- Make active use of benchmarking and profiling tools to measure,
+-- find the problems with, and improve the performance of your parser.

+-- An "immutable" buffer that supports cheap appends.
+--
+-- A Buffer is divided into an immutable read-only zone, followed by a
+-- mutable area that we've preallocated, but not yet written to.
+--
+-- We overallocate at the end of a Buffer so that we can cheaply
+-- append.  Since a user of an existing Buffer cannot see past the end
+-- of its immutable zone into the data that will change during an
+-- append, this is safe.
+--
+-- Once we run out of space at the end of a Buffer, we do the usual
+-- doubling of the buffer size.
+--
+-- The fact of having a mutable buffer really helps with performance,
+-- but it does have a consequence: if someone misuses the Partial API
+-- that attoparsec uses by calling the same continuation repeatedly
+-- (which never makes sense in practice), they could overwrite data.
+--
+-- Since the API *looks* pure, it should *act* pure, too, so we use
+-- two generation counters (one mutable, one immutable) to track the
+-- number of appends to a mutable buffer. If the counters ever get out
+-- of sync, someone is appending twice to a mutable buffer, so we
+-- duplicate the entire buffer in order to preserve the immutability
+-- of its older self.
+--
+-- While we could go a step further and gain protection against API
+-- abuse on a multicore system, by use of an atomic increment
+-- instruction to bump the mutable generation counter, that would be
+-- very expensive, and feels like it would also be in the realm of the
+-- ridiculous.  Clients should never call a continuation more than
+-- once; we lack a linear type system that could enforce this; and
+-- there's only so far we should go to accommodate broken uses.
