+      Chemtool is a program for drawing organic molecules. It runs under the X
+      Window System using the GTK widget set.
+
+      Most operations in chemtool can be accomplished using the mouse - the
+      first (usually the left) button is used to select or place things, the
+      middle button modifies properties (e.g. reverses the direction of a bond),
+      and the right button is used to delete objects.
+
+      The program offers essentially unlimited undo/redo, two text fonts plus
+      symbols, seven colors, drawing at several zoom scales, and square and
+      hexagonal backdrop grids for easier alignment.
