title: Platform-agnostic way to monitor filesystem events
body: <p>I'm currently developing a C++ application which should monitor the file system to reindex a set of files when they change. I am currently using Linux' inotify system, but would like the application to be as broadly portable to other systems as possible.</p>
  
  <p>Do you know of high-level, portable filesystem monitoring libraries, which would work at least on Linux and Mac OSX? (and have C or C++ bindings?)</p>
