Yet Another Diff Tool
YaDT - Yet another Diff Tool. It is another front-end for diff and in earlier versions diff3 utility. With YaDT you can compare and merge 2 and/or 3 files. YaDT is written on Tcl/Tk and wrapped in a single executable file with the help of sdx and tclkit. diff and cvs utilities are embedded inside YaDT. Also, YaDT supports Git and Mercurial repositories, but git and hg are not embedded inside YaDT, you should have git/hg executable in your path environment.
Free Version Control nt (no reason for nt, just a marker to give Tony Hoyle credit) the 'owner' of cvsnt has put up a paywall for sources. This project is made to provide a distribution point for the sources as last I was able to access them. Trunk from cvsnt.org and these branch tags 188.8.131.52.2382 184.108.40.206.2471 220.127.116.11.3744 Perhaps a community can grow around this project and continue development in its original vein.
