-
-One problem identified in the existing @sc{gdb/mi} output syntax was the
-difficulty in differentiating between a tuple such as:
-
-@example
-@{number="1",type="breakpoint",disp="keep",enabled="y"@}
-@end example
-
-where each value has a unique label, and a list such as:
-
-@example
-@{"1","2","4"@}
-@{bp="1",bp="2",bp="4"@}
-@end example
-
-where values are un-labeled or the label is duplicated.
-
-What follows is a draft revision to the output specification that
-addresses this problem.
-
-The output from @sc{gdb/mi} consists of zero or more out-of-band records
-optionally followed by a single result record, the result record being
-for the most recent command input. The sequence is terminated by
-@samp{(@value{GDBP})}.
-
-Asynchronous @sc{gdb/mi} output is similar.
-
-Each output record directly associated with an input command is prefixed
-by the input command's @code{@var{token}}.
