It's included with the new Apr-12 beta, it isn't one that you need to download separately.

But there isn't a button for it yet, to use it you need to set up a keyboard shortcut with Flip as the command, or use the new command name type-in by typing <tab> Flip <enter>.

It's mostly of use for fixing up a polygon mesh export of open surfaces, if your polygon program does not have a way to flip polygons without losing the good shading normals.
