+%description
+Iso2Mesh is a MATLAB/Octave-based mesh generation toolbox,
+designed for easy creation of high quality surface and 
+tetrahedral meshes from 3D volumetric images. It contains 
+a rich set of mesh processing scripts/programs, working 
+either independently or interacting with external free 
+meshing utilities. Iso2Mesh toolbox can directly convert
+a 3D image stack, including binary, segmented or gray-scale 
+images such as MRI or CT scans, into quality volumetric 
+meshes. This makes it particularly suitable for multi-modality 
+medical imaging data analysis and multi-physics modeling.
+Iso2Mesh is cross-platform and is compatible with both MATLAB 
+and GNU Octave.
