scummvm/sword2/logic.h
Torbjörn Andersson 7c9d46765b Removed some unnecessary / commented out code, and initialized the debug 
console a bit earlier so that error messages about missing files will be
more obvious to the user. (If an error happens that early, some of the
debugger commands will cause ScummVM to crash. I might look into that
later.)
