File::pushd - temporary chdir for a limited scope
Filepushd does a temporary chdir that is easily and automatically reverted. It works by creating a simple object that caches the original working directory. When the object is destroyed, the destructor calls chdir to revert to the original working directory. By storing the object in a lexical variable with a limited scope, this happens automatically at the end of the scope.
