+      Prooftree is a program for proof-tree visualization during interactive
+      proof development in a theorem prover. It is currently being developed
+      for Coq and Proof General. Prooftree helps against getting lost between
+      different subgoals in interactive proof development. It clearly shows
+      where the current subgoal comes from and thus helps in developing the
+      right plan for solving it.
+
+      Prooftree uses different colors for the already proven subgoals, the
+      current branch in the proof and the still open subgoals. Sequent texts
+      are not displayed in the proof tree itself, but they are shown as a
+      tool-tip when the mouse rests over a sequent symbol. Long proof commands
+      are abbreviated in the tree display, but show up in full length as
+      tool-tip. Both, sequents and proof commands, can be shown in the display
+      below the tree (on single click) or in a separate window (on double or
+      shift-click).
