+============
+Arno did a great work this summer!
+The pole-zero analysis has been corrected. The error was introduced 
+in an attempt to eliminate compiler warnings. The source has been 
+reworked and info file have been updated. As you may see, a new dir 
+called "spicelib" has been created, another step toward the separation
+of the simulator from the frontend.

+coding standard.
