+fixedint: simple fixed-width integers
+=====================================
+
+This module provides fixed-size integer classes which retain their fixed nature across
+arithmetic operations. It is geared towards users who need to emulate machine integers.
+
+It provides flexible classes for defining integers with a fixed number of bits, as well
+as predefined classes for common machine integer sizes. These classes can be used as
+drop-in replacements for int/long, and can be sliced to extract bitfields.
+
+Mutable versions of these integers are provided, enabling usages such as emulation of
+machine registers.
+
+
+
+Basic Usage
+===========
+
+A collection of predefined fixed-width integers for widths 8, 16, 32 and 64 are available
+in signed and unsigned varieties. Mutable and immutable versions of each type are provided.
+
+These are named as ``[Mutable][U]Int<N>``, e.g. ``UInt64`` or ``MutableInt8``. Use these
+classes as you would ``int``; arithmetic operations involving these classes will preserve
+fixed width. For example::
+
+    x = UInt32(0)
+    print(hex(~x)) # prints 0xffffffff
+
+Mutable instances can be modified in-place, preserving their type::
+
+    x = MutableUInt32(0)
+    y = x
+    x += 100
+    print(y) # prints 100
+
+To set a mutable integer without losing its type, use slicing::
+
+    x = MutableUInt32(0)
+    x[:] = -1
+    print(hex(x)) # prints 0xffffffff
+
+
+Arithmetic Operations
+=====================
+
+``FixedInt`` instances support all arithmetic operators. For binary operators, both
+operands are converted to plain Python ``int`` and then operated on. With a few
+exceptions, the result will be cast back to a ``FixedInt`` large enough to hold either
+operand, provided one of the operands was a ``FixedInt``. Note that the resulting
+``FixedInt`` may not be large enough to hold the complete result, in which case the
+result will be truncated.
+
+The exceptions are as follows:
+
+* ``divmod`` returns a tuple of plain ``int`` s
+* true division returns a float
+* ``**``, ``<<`` and ``>>`` will return a ``FixedInt`` if the left operand was a
+  ``FixedInt``, and plain ``int`` otherwise.
+
+Mutable instances additionally support in-place operations, which will modify the
+value without altering its type.
+
+
+Arithmetic operations between two integers of different sizes follow C integer promotion
+rules when determining the type of the final result. These rules boil down to the
+following:
+
+* If the operands are both signed, or both unsigned, the wider of the two operand types is chosen.
+* Otherwise, if the unsigned operand is wider, the unsigned operand is chosen.
+* Otherwise, the signed operand is chosen.
+
+
+
+
+Slicing
+=======
+
+``FixedInt`` instances support slicing. Slicing with a single integer produces a single
+Boolean value representing the bit at that position. Slicing with a range produces a
+``FixedInt`` containing the range of bits. Mutable instances additionally support slice
+assignment. This makes e.g. manipulating a flag register straightforward, without needing
+to use bitwise operations.
+
+All indexing operations treat the least-significant bit (LSB) as bit 0. Currently, only
+contiguous bit sections can be obtained; for more flexibility consider using a module
+such as `bitarray`.
+
+Getting a slice results in a ``FixedInt`` instance with exactly as many bits as the range.
+This can be used to perform wraparound arithmetic on a bit field.
+
+Slices support two main syntaxes::
+
+    value[<start>:<end>]
+    value[<start>:<length>j]
+
+The latter syntax is more convenient when dealing with fixed-width fields. Both of the
+slice arguments may be omitted, in which case they will default to the LSB and MSB of
+the ``FixedInt`` respectively.
+
+
+
+Byte Conversion
+===============
+
+``FixedInt`` instances can be converted to and from raw byte representations by using the
+``.to_bytes`` instance method and the ``.from_bytes`` classmethod. The usage of these
+methods matches that of Python 3.4's ``int.to_bytes`` and ``int.from_bytes`` methods.
