+		SPAMS (SPArse Modeling Software) is an optimization toolbox for solving
+		various sparse estimation problems, such as: Dictionary learning and
+		matrix factorization (NMF, sparse PCA, ...); solving sparse decomposition
+		problems with LARS, coordinate descent, OMP, SOMP, proximal methods; and 
+		Solving structured sparse decomposition problems (l1/l2, l1/linf, sparse
+		group lasso, tree-structured regularization, structured sparsity with
+		overlapping groups,...).
