wip/roswell 26.02.116 NetBSD

Roswell is a Lisp implementation installer/manager, launcher, and much more! It started out as a command-line tool with the aim to make installing and managing Common Lisp implementations really simple and easy. It has now evolved into a full-stack environment for Common Lisp development, and has many features that makes it easy to test, share, and distribute your Lisp applications. With Roswell, we aim to push the Common Lisp community to a whole new level of productivity. While technically still in beta, the basic interfaces are stable and not likely to change.
