Taking a quick look that's just the documentation for Mac??
While the documentation went out as part of the Mac release, most recent shipping product, it was designed to cover both platforms (Windows and Mac) instead of having two distinctly different documentation sets. It is a different approach than what we have done in the past. Each topic (concept or reference) denotes which platform it is related to.
I am curious as to any opinions or comments anyone might have on this approach, and anything else you feel might be missing from the AutoLISP documentation.
