cwdiff
What it is
cwdiff is a command-line tool that wraps wdiff to compare directories and display differences in color. It is listed for Linux command-line use and is free, with a plan price of free. Users can configure it as a Mercurial extdiff command and run it with `hg wdiff`; adding `--no-color` to the wdiff options disables color output. The project is a shell-language repository. Listed download options include a tarball and packages for MacPorts, Arch Linux AUR, NetBSD, and Gentoo. A NetBSD package page offers a binary package for NetBSD 10.0, version 0.4.0, and lists no runtime dependencies. The project documentation is hosted on junghans.github.io, and the repository directs bug reports to GitHub Issues. The repository is associated with maintainer Christoph Junghans, whose profile lists Los Alamos, New Mexico, USA. The NetBSD package page lists GNU GPL version 2 as its license.
