/** \class cmWorkingDirectory
* \brief An RAII class to manipulate the working directory.
* The current working directory is set to the location given to the
* constructor. The working directory can be changed again as needed
* by calling SetDirectory(). When the object is destroyed, the destructor
* will restore the working directory to what it was when the object was
* created, regardless of any calls to SetDirectory() in the meantime.

* \c errno value associated with the failure. A description
