+You can implement new @value{GDBN} parameters using Python.  A new

+@code{show} commands.
+
+@defmethod Parameter __init__ name @var{command-class} @var{parameter-class} @r{[}@var{enum-sequence}@r{]}
+The object initializer for @code{Parameter} registers the new
+parameter with @value{GDBN}.  This initializer is normally invoked
+from the subclass' own @code{__init__} method.
+
+@var{name} is the name of the new parameter.  If @var{name} consists

+an exception is raised.
+
+@var{command-class} should be one of the @samp{COMMAND_} constants

+categorize the new parameter in the help system.
+
+@var{parameter-class} should be one of the @samp{PARAM_} constants

+parameter; this information is used for input validation and
+completion.
+
+If @var{parameter-class} is @code{PARAM_ENUM}, then
+@var{enum-sequence} must be a sequence of strings.  These strings
+represent the possible values for the parameter.
+
+If @var{parameter-class} is not @code{PARAM_ENUM}, then the presence
+of a fourth argument will cause an exception to be thrown.

+User convenience variables, et cetera, have associated types.  Normally these
+types live in the associated objfile.  However, when the objfile is unloaded,
+those types are deep copied to global memory, so that the values of the user
+variables and history items are not lost.  During the copy they will get their
+@code{TYPE_OBJFILE} set to @code{NULL} and become so-called @dfn{reclaimable}
+types.
+
+Types with null @code{TYPE_OBJFILE} can be either permanent types
+(@pxref{Builtin Types}) or reclaimable types which will be deallocated at the
+first idle @value{GDBN} moment if the last object referencing them is removed.
+Permanent types are allocated by the function @code{alloc_type} (and its
+derivations like @code{init_type}) specifying objfile as @code{NULL}.  The
+reclaimable types are created the same way but moreover they need to have
+@code{type_init_group} called to start their tracking as being possibly
+deallocatable.
+
+@findex free_all_types
+When @value{GDBN} gets idle it always calls the @code{free_all_types} function
+which deallocates any unused types.  All types currently not owned by an
+objfile must be marked as used on each @code{free_all_types} call as they would
+get deallocated as unused otherwise.
+
+@code{free_all_types} automatically checks for any cross-type references such
+as through @code{TYPE_TARGET_TYPE}, @code{TYPE_POINTER_TYPE} etc.@: and
+prevents early deallocation for any such existing references.  Reclaimable
+types may reference any other reclaimable types or even permanent types.  But
+permanent types must not reference reclaimable types (nor an objfile associated
+type).
