Please do not make feature requests! I'll just close the issue. Please don't take it the wrong way---if you want something, I'm happy to work with your efforts to patch the existing system.
Alternatively, if you wish to fund development for particular features, please contact me privately.
slant is a remote system monitor. For the time being, it only works with OpenBSD hosts, though Linux is technically working (if still under development).
The website has all the information you might need, and the manpages document the system itself. The GitHub site is for issues and pull requests, as the source code is versioned in a private BSD.lv repository.
If you'd like to help out, please e-mail me or just dive right in with a pull request.
