+Colors
+------
+The generated files uses the following color conventions:
+
+.. glossary::
+     Black 
+        The outer edges of a part
+     Blue
+        Inner edges of a part
+     Red
+        Comments or help lines that are not ment to be cut or etched
+     Green
+        Etchings
+
+Normaly you will cut things in the order: Green, Blue, Black. If other 
+colors are present, the meaning should hopefully be obvious.
