Some of these directories come from entire outside repositories brought in using git-subtree. This means that the source files are inserted directly into the rippled repository. They can be edited and committed just as if they were normal files.
However, if you create a commit that contains files both from a subtree, and from the ripple source tree please use care when designing the commit message, since it will appear in the subtree's individual repository when the changes are pushed back to the upstream.
When submitting pull request, make sure that any commits which include files from subtrees are isolated - i.e. do not mix files from subtrees and ripple in the same commit. This way, the commit message will make sense. We don't want to see "Fix pathfinding bug with XRP" appearing in the LevelDB or Beast commit log, for example.

Ripple's fork of protobuf. We've changed some names in order to support the unity-style of build (a single .cpp addded to the project, instead of linking to a separately built static library).

NOTE Linux builds use the protobuf installed in /usr/lib. This will be fixed in a future revision.
Not technically a subtree but included here because it is a direct copy of the official SQLite distributions available here:
