@echo off

:: In several old L4D2 builds, we currently have some weird black magic we don't
:: fully understand to do what looks like DRM circumvention or... something.
:: Annoyingly, that black magic manages to break regular use of Steam after the
:: game exits. This is fixed by setting a registry key back to Steam's PID.

:: The scripts used to launch those builds already do this, of course, but if
:: you're launching L4D2 under a debugger, you can use this script instead.

:: By the way, if anyone wants to look into solving the root cause so that none
:: of this is needed any more, that would be cool!
