Installation of sub tree (at the root of the project) :

    git remote add db_sdk_remote git@github.com:dlgg/DropboxTCL.git
    git fetch db_sdk_remote
    git checkout -b dropbox db_sdk_remote/master
    git checkout master
    git read-tree --prefix=includes/dropbox/ -u dropbox
    git pull -s subtree db_sdk_remote master (if it doesn't work : git checkout dropbox; git pull; git checkout master)
    git merge --squash -s subtree --no-commit dropbox

Update of dropbox sdk :

    git pull -s subtree db_sdk_remote master

Check if need to update dropbox sdk :

    git diff-tree -p dropbox
    git diff-tree -p db_sdk_remote/master
