I just picked up the book &quot;Tcl&#x2F;Tk: A Developer&#x27;s Guide&quot; by Clif Flynt. I see Tcl&#x2F;Tk in PureData, Pd, that I am using, and so many other apps that I decided it was worth learning. The short code examples were also enlightening. I have used it so far to write some utilities on Windows that I would have used Powershell for, but now I can use them on my Linux partition too. And the Tk widgets are not as bad as the press they get, especially for personal, rather than distribution to the &#x27;design&#x27; saavy ;) I like it so far.
