Just a few notes:

* The tkscript example seems to have lost all indentation, and I think
  that the info relating to 1.6.0 can be safely lost by now.

* Tktable can be handled more easily using callbacks in R-1.7.x. I
  have an example somewhere on the laptop, I think. Interfacing to Tcl
  arrays is quite a pain as I'm sure you already found out; something
  I hope to straighten out in the future.

* You're describing the pack manager as superseded by the grid
  manager, which I think is not quite right. Both are useful in
  different contexts; some layouts are really awkward to lay out
  on a grid, so knowing the pack manager can pay off.

Re. examples and screenshots, you might be better off just taking
examples and doing your own screenshots. Things get more consistent
that way. A few examples of how things look like in the Linux
interface might be useful, though (maybe Aqua too, anyone?)
