The output from GDB/MI consists of zero or more out-of-band records followed, optionally, by a single result record. This result record is for the most recent command. The sequence of output records is terminated by `(gdb)'.
If an input command was prefixed with a token
then the
corresponding output for that command will also be prefixed by that same
token.

depending on the needs--this is still in development).

token ==>
Notes:
token
is from the corresponding request. If an execution
command is interrupted by the `-exec-interrupt' command, the
token associated with the `*stopped' message is the one of the
original execution command, not the one of the interrupt command.
