+<h1>Convert an DFII technology file into KLayout format</h1>
+
+Start the Cadence icfb tool and call the "Technology Tool Box". Then press the "Dump" 
+button in the tool box. In the "Technology Library" pulldown select the OA technology library
+you want to dump. Please make sure that that you only switch the "layerDefinitions" toggle
+to "On". Fill out the textbox with name of the output ASCII technology file. Then push the "OK"
+button to write out the technology file.
+
+<p>
+<img src="df2_NCSU_Techlib_tsmc02_laydefs.gif"> 
+<p>
+Then locate the current "display.drf" file in the virtuoso run directory. It coIf not found then
+please take a look at the technology directory, which should contain the original version of
+the display.drf file. The display.drf file contains color and layer visibility and style 
+defintions, fill pattern and line style information.
+
+As third item we need a copy of the OpenAccess stream layer map file. It should reside in the
+technology library and is usually called "streamin.layermap". It will contain a mapping
+between OA layer/OA purpose to GDSII layer number and GDSII datatype. Here is an exmaple:

+# -------------     ---------------------       -----------
+# Layer Name        Layer purpose               GDSII layer
