+MONGOOSE is a package for structural analysis and refinement of constraint-based metabolic networks.
+Unlike other existing softwares, MONGOOSE uses exact rational arithmetic, which makes its results
 certifiably accurate. The MetaMerge algorithm (Chindelevitch et al, Genome Biology 2012,
 13:r6, http://genomebiology.com/2012/13/1/r6), is based on and fully integrated with MONGOOSE.
