+@tindex Parameter
+You can implement new @value{GDBN} parameters using Python. A new
+parameter is implemented as an instance of the @code{gdb.Parameter}

+@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
+of multiple words, then the initial words are looked for as prefix
+commands. In this case, if one of the prefix commands does not exist,
+an exception is raised.
+
+@var{command-class} should be one of the @samp{COMMAND_} constants

+@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.
+
+The help text for the new parameter is taken from the Python
+documentation string for the parameter's class, if there is one. If
+there is no documentation string, a default value is used.

+class.
+

+Create a new breakpoint. @var{location} is a string naming the
+location of the breakpoint. The contents can be any location
+recognized by the @code{break} command.
+@end defmethod
+
+@defmethod Breakpoint is_valid
+Return @code{True} if this @code{Breakpoint} object is valid,
+@code{False} otherwise. A @code{Breakpoint} object can become invalid
+if the user deletes the breakpoint. In this case, the object still
+exists, but the underlying breakpoint does not.
+@end defmethod

+@defivar Breakpoint enabled
+This attribute is @code{True} if the breakpoint is enabled, and
+@code{False} otherwise. This attribute is writable.
+@end defivar

+@defivar Breakpoint silent
+This attribute is @code{True} if the breakpoint is silent, and
+@code{False} otherwise. This attribute is writable.
+
+Note that a breakpoint can also be silent if it has commands and the
+first command is @code{silent}. This is not reported by the
+@code{silent} attribute.
+@end defivar

+@defivar Breakpoint thread
+If the breakpoint is thread-specific, this attribute holds the thread
+id. If the breakpoint is not thread-specific, this attribute is
+@code{None}. This attribute is writable.
+@end defivar

+@defivar Breakpoint ignore_count
+This attribute holds the ignore count for the breakpoint, an integer.
+This attribute is writable.

+This attribute holds the breakpoint's number -- the identifier used by
+the user to manipulate the breakpoint. This attribute is not writable.
+@end defivar
+
+@defivar Breakpoint hit_count
+This attribute holds the hit count for the breakpoint, an integer.
+This attribute is writable, but currently it can only be set to zero.
+@end defivar
+
+@defivar Breakpoint location
+This attribute holds the location of the breakpoint, as specified by
+the user. It is a string. This attribute is not writable.
+@end defivar
+
+@defivar Breakpoint condition
+This attribute holds the condition of the breakpoint, as specified by
+the user. It is a string. If there is no condition, this attribute's
+value is @code{None}. This attribute is writable.
+@end defivar
+
+@defivar Breakpoint commands
+This attribute holds the commands attached to the breakpoint. If
+there are commands, this returns a string holding all the commands,
+separated by newlines. If there are no commands, this attribute is

+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

+@findex free_all_types

+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
