+Contrary to the experience of most developers, who tend to work on UNIX-based
+systems, a signficant portion of omics analysis today happens on Windows
+(generally, on desktops using something like R Studio). To ensure that the

+all major operating systems (Windows, Mac, and Linux) when possible. Further,
+this fact should be verified by CI/CD.

+Note that, in some cases, cross-platform compatibility won't be possible (e.g.,
+if you're writing a crate that is specific to a particular operating system).
+In these cases, it's okay to not design or test your crate across operating
+systems. Ultimately, the intent of this value is to encourage cross-platform
+design when it is possible.
