I'm dorothyr. I've been messing around with Tcl/Tk way longer than anyone should.

I maintain TkRev (formerly TkCVS) and I maintained TkDiff for a few years. Recently I tried to use TkMan and discovered that it didn't work with Tk > 8.4 and it seems to be completely abandoned, so I fixed the text widget issues and forked it as TkReadMan.

The Tcl/Tk projects I work on:

TkRev https://sourceforge.net/projects/tkcvs

TkDiff https://sourceforge.net/projects/tkdiff

TkReadMan https://sourceforge.net/projects/tkread
