title: Handling file paths cross platform
body: <p>Do any C++ GNU standalone classes exist which handle paths cross platform?  My applications build on Windows and LInux.  Our configuration files refer to another file in a seperate directory.  I'd like to be able to read the path for the other configuration file into a class which would work on both Linux or Windows.</p>
  
  <p>Which class would offer the smallest footprint to translate paths to use on either system?  Thanks</p>
