Made the 'data' member optional in node_ref - it's only created on-demand, so we don't waste extra memory every time we do Value tmp = v;

Switched memory to using shared nodes, and node_data to keep only naked node pointers, not shared nodes (to break the cycle, and we don't need weak pointers because their memory is guaranteed to exist, via 'memory')

Switched the 'pragma once' to only happen on MSVC, or gcc >= 3.4 (it was causing trouble on the sun compiler)

Marked Parser, Emitter, Node, Iterator, Mark, and Null for exporting to a DLL. It appears to work properly, although VS gives me lots of warning C4251 since I didn't export all data members of each of the above classes.

It seems that it's not necessary to export those members (as long as you can't access them), and most of them are STL instances, which apparently cause lots of problems for DLLs. (For example, you simply can't export instances of std::map; see http://support.microsoft.com/kb/168958.)

Fixed folding bug (detecting indentation, example 8.2), and clipping/stripping empty strings (example 8.6)

Added explicit doc start/end tokens for the emitter, and set it so that if you try to write after you've already written a full doc, it writes a doc start and continues

Refactored bool emitting to make it 1) correct for the short bool form and 2) not barf on early versions of VS

Flipped the include guard and the pragma, and don't use the pragma for early versions of gcc (< 3.4)

Moved the local structs from Emitter::Write(bool) to an anonymous namespace in the hopes that Visual Studio <= 2003 will be happy

Merged contrib folders from the graphbuilder-api branch, including the recursive search in CMakeLists.txt

Switched exception constants to const char * const (from const std::string) so we don't have to construct them all in every translation unit, and switched the exception class to derive from std::runtime_error (so it handles what() for us)
