+We include the tech file for SCN3ME_SUBM in the tech directory,

+You can use this interactively by appending the magic system path in 
+your .magicrc file
+path sys /Users/mrg/openram/technology/scn3me_subm/tech
 
+We require the version 30 Magic rules which allow via stacking.
+We obtained this file from Qflow ( http://opencircuitdesign.com/qflow/index.html )
+and include its appropriate license.
