I added a little snippet for a CMakeLists.txt that compiles it.

/me pulls out "BUGS in Writing". Ah, yes. I killed all but 3 whiches
that were wrong, which left two that I think are just introducing
additional information, and one that shows which contexts are
completely different - perhaps that one should be replaced by "what"?
(dumping the AST nodes will show *which | what* nodes are already

I found 2 instances of "interested" in the text; both reworded
according to your suggestion.

Really? Wouldn't that then say that all TypeLoc nodes ... Oh, forget
it, I'm stupid. Yep, putting that back in again. Now that leaves me
with 4 whiches. Please let me know if one of them is still incorrect.

Hm. I'm not sure that this is exactly what I meant to say (it sounds
better though, so I'm fine with it :)

I find it useful to format names of code entities that appear in running text in the code font to emphasize their "program-ness"; similarly, code snippets in running text work better in the code font. By comparison, concepts like "an AST" should be text font -- even thought the type AST would show up in code font. It's a bit of a pain to format documents this way, but it does improve clarity.
I want to do more formatting, but later. I'm a launch and iterate guy
:) I think it's much more important to have all the information out
*first*, and then go and make it all pretty, create some coloring
scheme, link everything to the doxygen etc. But, as I said, content
Thx a lot for the review!
