Tracepoint.c:
This module defines the following debugger commands:
trace : set a tracepoint on a function, line, or address.
info trace : list all debugger-defined tracepoints.
delete trace : delete one or more tracepoints.
enable trace : enable one or more tracepoints.
disable trace : disable one or more tracepoints.
actions : specify actions to be taken at a tracepoint.
passcount : specify a pass count for a tracepoint.
tstart : start a trace experiment.
tstop : stop a trace experiment.
tstatus : query the status of a trace experiment.
tfind : find a trace frame in the trace buffer.
tdump : print everything collected at the current tracepoint.
save-tracepoints : write tracepoint setup into a file.
This module defines the following user-visible debugger variables:
$trace_frame : sequence number of trace frame currently being debugged.
$trace_line : source line of trace frame currently being debugged.
$trace_file : source file of trace frame currently being debugged.
$tracepoint : tracepoint number of trace frame currently being debugged.

Our response will be different, depending on FROM_TTY:
If FROM_TTY is true, meaning that this command was
typed interactively by the user, then give an error

However if FROM_TTY is false, meaning that we're either

The rationalle is that if you typed the command, you
might just have committed a typo or something, and you'd
like to NOT lose your current debugging state. However
if you're in a user-defined command or especially in a
