+LMM paper - Bates, Maechler, Bolker and Walker
+
+1. Introduction (done)
+  * Motivation
+  * Model and notation
+
+2. Derivation of the modified Henderson's MME and profiled log-likelihood (done)
+
+3. Implementation of PLS solution in pure R (and in Julia)
+  * lme4-1.0 uses compiled code
+  * getME function to extract objects of interest
+	* VarCorr, pre-computation of Z'WZ, ...
+
+4. Special cases
+  * a single scalar r.e. term -> diagonal Lambda and L
+	* a single vector-valued r.e. term -> block-diagonal Lambda and L
+	* nested grouping factors -> no fill-in, permutation on post-order only
+	* scalar, not necessarily nested model -> diagonal updates
+
+5. Profiling parameters and graphical presentation
+
+6. Modularization?
