Loads a single user program into gdb's symbol table, removing

the previous user program loaded if one exists.

Usage: load-userprogram <path-to-prog>

document auto-userprogram
|
|
Calls load-userprogram on whatever is curproc->p_name. It is meant
|
|
to work with kernels that set p_name to an absolute path to the
|
|
program, and it is designed to be called from hook-stop.
|
|
Usage: auto-userprogram
