+       New: There are now functions 
+       <code class="member">SparsityPattern::copy_from</code> and
+       <code class="member">SparseMatrix::copy_from</code>
+       that can be used to construct sparsity patterns and matrix at
+       once, i.e. without setting up a sparsity pattern element by
+       element, possibly after using a way too large value for the
+       maximal row length, then calling 
+       <code class="member">SparsityPattern::compress</code> etc.
