For many years I have written pages about the Tcl programming language in the Tclers' Wiki http://wiki.tcl.tk/RS , and more than once I have been asked to make a book from them. I never managed, until I found WikiBooks. Maybe here it will come to life - and be free for all, as the original pages were, but better structured and less cluttered by crosstalk :)

Wikipedia, and I assume WikiBooks too, has a clearer separation between presentation and discussion, than our Tclers' Wiki has. But I'll continue to write there, whenever I have something interesting to report - and later see to integrate useful content into Programming:Tcl.
