-
-Constants
----------
-
-- ``true`` and ``false`` are the :ref:`boolean constants
-  <lang-booleanvariables>`.
-
-Control Flow
-------------
-
-- ``break`` can exit out of a :ref:`switch statement
-  <lang-switchcase>` or a :ref:`for <lang-for>`, :ref:`do
-  <lang-dowhile>`, or :ref:`while <lang-while>` loop.
-
-- ``case`` defines alternatives in a :ref:`switch statement <lang-switchcase>`.
-
-- ``continue`` will move control flow to the next iteration of the
-  enclosing :ref:`for <lang-for>`, :ref:`do <lang-dowhile>`, or
-  :ref:`while <lang-while>` loop.
-
-- ``default`` defines the default alternative in a :ref:`switch
-  statement <lang-switchcase>`.
-
-- ``do`` introduces a :ref:`do <lang-dowhile>` loop.
-
-- ``else`` is used in :ref:`if statements <lang-if>`.
-
-- ``for`` introduces a :ref:`for <lang-for>` loop.
-
-- ``goto`` :ref:`jumps <lang-goto>` to a label.
-
-- ``if`` introduces an :ref:`if statement <lang-if>`.
-
-- ``return`` :ref:`transfers flow to a function's caller <lang-return>`.
-
-- ``switch`` introduces a :ref:`switch statement <lang-switchcase>`.
-
-- ``while`` introduces a :ref:`while <lang-while>` loop.
-
-Types
------
-
-The following keywords are used for built-in types.
-
-- :ref:`bool <lang-booleanvariables>`
-- :ref:`char <lang-char>`
-- :ref:`double <lang-double>`
-- :ref:`float <lang-float>`
-- :ref:`int <lang-int>`
-- :ref:`long <lang-long>`
-- :ref:`short <lang-built-in-types-integral>`
-- :ref:`void <lang-void>` (not really a type, but used in the absence
-  of one)
-
-The following keywords are used to introduce new types.
-
-- :ref:`enum <lang-enum>`
-
-Qualifiers
-----------
-
-- :ref:`static <lang-static>` can be used to declare persistent local
-  variables; it has other uses not documented here.
-
-- ``unsigned`` is used to specify an unsigned integral type.
-  Examples: :ref:`lang-unsignedint`, :ref:`lang-unsignedchar`.
-
-- :ref:`volatile <lang-volatile>` is useful when declaring variables
-  that may be modified by external interrupts.
-
-- :ref:`const <lang-const>` is used to define constants.
-
-Other
------
-
-These keywords are not described in the Maple documentation.  For more
-information, consult a C++ reference.
-
-- ``asm`` is used to insert literal assembly language.
-
-- ``auto`` is used to declare that a variable has automatic storage.
-
-- ``catch`` is used in exception handling.  Note that the default
-  flags we pass to :ref:`GCC <arm-gcc>` include ``-fno-exceptions``.
-
-- ``class`` is used to define classes.
-
-- ``const_cast`` is used in typecasting.
-
-- ``delete`` is used to free ``new``\ -allocated storage.  Note that
-  dynamic memory allocation is not available by default on the Maple,
-  so you'll have to bring your own ``new`` and ``delete`` if you want
-  this.
-
-- ``dynamic_cast`` is used in typecasting.
-
-- ``explicit`` is used to declare constructors that can be called only
-  explicitly.
-
-- ``export`` declares a template definition accessible to other
-  compilation units.
-
-- ``extern`` can mark a declaration as a declaration and not a
-  definition, and also grant external linkage to a ``const`` or
-  ``typedef``.
-
-- ``friend`` is used to declare that certain functions have access to
-  a class's private variables.
-
-- ``inline`` is a compiler hint to inline a function.
-
-- ``mutable`` specifies that a member can be updated, even when a
-  member of a ``const`` object.
-
-- ``namespace`` declares a new namespace.
-
-- ``new`` dynamically allocates space for a value.  Note that dynamic
-  memory allocation is not available by default on the Maple, so
-  you'll have to bring your own ``new`` and ``delete`` if you want
-  this.
-
-- ``operator`` is used to define type-specific operator overrides.
-
-- ``private`` declares a private class member.
-
-- ``protected`` declares a protected class member.
-
-- ``public`` declares a public class member.
-
-- ``register`` is a compiler hint to store a variable in a register.
-
-- ``reinterpret_cast`` is used in typecasting.
-
-- ``signed`` is the opposite of ``unsigned``.
-
-- ``static_cast`` is used in typecasting.
-
-- ``struct`` declares a new struct.
-
-- ``template`` introduces a template class, function, etc.
-
-- ``this`` is a pointer to the receiver object.
-
-- ``throw`` is used in exception handling.  Note that the default
-  flags we pass to :ref:`GCC <arm-gcc>` include ``-fno-exceptions``.
-
-- ``try`` is used in exception handling.  Note that the default
-  flags we pass to :ref:`GCC <arm-gcc>` include ``-fno-exceptions``.
-
-- ``typedef`` defines a type synonym.
-
-- ``union`` defines an untagged union.
-
-- ``using`` is a directive related to namespaces.
-
-- ``virtual`` declares a method which may be overridden.
-
-- ``wchar_t`` is the wide character type.
