annotate deps/Platinum/ThirdParty/Neptune/Source/Core/NptDataBuffer.h @ 9:05c88622db6b default tip

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
- Adhoc transcoder now doesn't rely on Platinum - Moved the adhoc transcoder to the main source tree; it can be moved back into test once it's more stable
