                  <br><br>Technically, <b>xrsh</b> is a bundle of freshly created re-usable FOSS WebXR components.<br>These provide a common filesystem interface for interacting with WebXR, offering the well-known linux/unix toolchain including a commandline to invoke, store, edit and run WebXR utilities - regardless of their implementation.
                  <br><br>Think of it as termux for the VR/AR headset browser, which can be used to e.g. livecode (using terminal auto-completion!) for XR component (registries).
