+THE VVP TARGET
+
+SYMBOL NAME CONVENTIONS
+
+There are some naming conventions that the vp target uses for
+generating symbol names.
+
+* wires and regs
+
+Nets and variables are named V_<full-name> where <full-name> is the
+full hierarchical name of the signal.
+
+* Logic devices
+
+Logic devices (and, or, buf, bufz, etc.) are named L_<full_name>. In
+this case the symbol is attached to a functor that is the output of
+the logic device.
