[c-nsp] OT: TCL Book recommendation for Cisco EEM

[Justin Shore]

Does anyone have any suggestions on a good book on TCL scripting for 
Cisco's EEM?  As a complete TCL novice, a good TCL intro would be good. 
  I can probably use existing EEM examples to learn the intricacies of 
using TCL for Cisco I think, unless someone knows of a book that covers 
that too.
