libfile-pushd-perl 1.001-1 (i386 binary) in ubuntu quantal

 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.
 .
 This is very handy when working with temporary directories for tasks like
 testing; a function is provided to streamline getting a temporary directory
 from File::Temp.
