+GENERATING 1-BEST SEGMENTATIONS AND LATTICES
+------------------------------------------------------------------------------
+
+Here are some sample invokations:
+
+  ./compound-split.pl --output 1best < infile.txt > out.1best.txt
+      Segment infile.txt according to the 1-best segmentation file.
+
+  ./compound-split.pl --output plf < infile.txt > out.plf
+
+  ./compound-split.pl --output plf --beam 3.5 < infile.txt > out.plf
+      This generates denser lattices than usual (the default beam threshold
+      is 2.2, higher numbers do less pruning)
+
+
+MODEL TRAINING (only for the adventuresome)
+------------------------------------------------------------------------------
+
+I've included some training data for training a German language lattice
+segmentation model, and if you want to explore, you can or change the data.
+If you're especially adventuresome, you can add features to cdec (the current
+feature functions are found in ff_csplit.cc).  The training/references are
+in the file:
+
+               dev.in-ref
+
+The format is the unsegmented form on the right and the reference lattice on
+the left, separated by a triple pipe ( ||| ).  Note that the segmentation
+model inserts a # as the first word, so your segmentation references must
+include this.
+
+To retrain the model (using MAP estimation of a conditional model), do the
+following:
+
+  cd de
+  ./TRAIN
+
+Note, the optimization objective is supposed to be non-convex, but i haven't
+found much of an effect of where I initialize things.  But I haven't looked
+very hard- this might be something to explore.
