+  This Python library demonstrates the use of the GSI/Python binding
+  API for developing "bridge" applications - i.e. libraries that access
+  the KLayout objects through their C++ API.
+
+  This sample library provides two conversion functions:
+
+    bridge.p2a(poly)    Converts pya.DSimplePolygon objects to Python
+                        arrays with the structure [ (x, y), ... ].
+
+    bridge.a2p(array)   Does the inverse transformation
+
+  Use cases for such libraries are fast C++ based conversion of KLayout
+  objects into other objects and vice versa.
