Ebook: Tcl/Tk, Second Edition: A Developer's Guide (The Morgan Kaufmann Series in Software Engineering and Programming)

When I needed to write some TCL for an EDA test bench and for FPGA syntheses I ran into the issue that TCL has a significant structure than other languages such as non-object oriented Perl. Because of this I didn't know for what to search. After reading this book I was able to know the questions I needed to ask.
