perl-file-pushd 1.016 Change directory temporarily for a limited scope
File::pushd does a temporary
chdir that is easily and automatically reverted, similar to
pushd in some Unix command shells. It works by creating an 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.
