-"""
-Spawn GDB, connect to QEMU's GDB server, and read test states from that.
-
-We need two scripts (this one and the primary `qemu_tool.py`) because we can't
-pass arguments to scripts executed via `gdb -x <script>`.
-
-This script (`verify_qemu.py`) is the one the user interfaces with. It
-eventually calls `execv` to spawn a GDB process that calls the main
-`qemu_tool.py` script; `python verify_qemu.py` essentially behaves as if
-something like `gdb --batch -x qemu_tool.py` were executed instead. Before it
-starts GDB, though, it parses command line arguments and applies some weird but
-necessary logic to pass them to `qemu_tool.py`.
