DESCRIPTION = '''
A simple tool that patches out the code that forces any
of the Halo 2 tools to close when it hits an assertion.

Should work for all H2EK exes except the "fast" versions.

Combining this with the following .bat script allows you
to use any of the tools completely without assertion messageboxes:
```
set DONT_TREAD_ON_ME_WITH_DEBUGGING_DIALOGS=TRUE
set DONT_SPAWN_TOOL_FOR_UPLOADS=TRUE
start halo2_tag_test.exe
```

; Starts Halo 2 tag test while keeping debug messageboxes disabled.
; Combined with the patch from h2ek_tools_assertion_exit_patch.py
; this should effectively disable assertion errors.
