echo Loading Kernel GDB Macros package. Type "help kgm" for more info.\n
| These are the kernel gdb macros. These gdb macros are intended to be
| used when debugging a remote kernel via the kdp protocol. Typically, you
| would connect to your remote target like so:
-| (gdb) target remote-kdp
-| (gdb) attach <name-of-remote-host>
+| (gdb) target remote-kdp
+| (gdb) attach <name-of-remote-host>
