DDG - 2020-11-20: chesschart was in fact created as a toy example for presenting the tmdoc::tmdoc literate programming tool at the 2020 Tcl/Tk Conference. The complete presentations can be seen on youtube here: https://www.youtube.com/watch?v=lfIPM5eyuVA

DDG - 2020-12-03: version 0.2 fixes the pkgIndex.tcl file, adds colors for lines, splines, user defined coordinate systems and adds a background argument to allow canvas::snap create always figures of the same size. An tutorial made with tmdoc::tmdoc was added as well: tutorial
