"Invoke the trepan3k Python debugger and start the Emacs user interface.

String OPT-CMD-LINE is treated like a shell string; arguments are
|
|
tokenized by `split-string-and-unquote'. The tokenized string is
|
|
parsed by `trepan3k-parse-cmd-args' and path elements found by that
|
|
are expanded using `realgud:expand-file-name-if-exists'.
|
|
|
|
Normally, command buffers are reused when the same debugger is
|
|
reinvoked inside a command buffer with a similar command. If we
|
|
discover that the buffer has prior command-buffer information and
|
|
NO-RESET is nil, then that information which may point into other
|
|
buffers and source buffers which may contain marks and fringe or
|
|
marginal icons is reset. See `loc-changes-clear-buffer' to clear
|
|
fringe and marginal icons.
