-<p>\"A complete rewrite of legacy science software, with a specific
-focus on clarity, can prove useful. It uncovers bugs, provide a
-definitive statement of the underlying algorithm, lets scientists
-easily pose and answer new research questions, makes it easier to
-develop new visualizations and other interfaces, and makes the code
-considerably more accessible to interested third parties and the
-public.\"</p>

-<p>The YAC development started as a pilot study to investigate the
-coupling between unstructured meshes which gradually turned into a mature
-fully parallelised coupling software. Rather than implementing all
-required functionality directly into an existing coupler like OASIS4
-we decided to ground our effort on a light weight software
-infrastructure. YAC2 is a redesign of YAC1. All interpolation methods
-available in YAC1 are supported with YAC2. In contrast to YAC1 halo
-information is no longr required. In order to keep the software light
-we still stick to:</p>

-        Only unstructured and fully regular grids are supported directly.<br />
-        Internally, grid information and exchange fields are handled as double.<br />
-        Fortran reals are converted to double precision before delivering it to the C world.<br />
