Surfing REB Index files
So, you want to build your own code to surf the REB? Here's where to find the official parser of the REB.
Run REBOL/View, and look in the Viewtop/Docs/Developer folder. You will see a file called "REB Index". Click it for a demo, then right click and "edit" it to view the source code for parsing a REB index file. This is the actual code that does it, so this code provides the official spec of a REB index.
Or, you can also get it with:
write %reb-index.r read http://www.rebol.com/view/docs/developer/reb-index.r
So... where is that REB search engine you've been promising? With this code, it should be easy to get started on it. (Hint hint)
