// Synchronize (by uploading) the local directory tree rooted at "qa_data/sftpUploadTree"
// with the remote directory tree rooted at "syncUploadTest"
// Both directories are relative paths.  The remote directory
// is relative to the HOME directory of the SSH user account.
// The local directory is relative to the current working directory of the process.
// It is also possible to use absolute paths.

string remoteDir = "syncUploadTest";
string localDir = "qa_data/sftpUploadTree";

// Possible modes that can be passed to the SyncTreeUpload method are:
// mode=0: Upload all files
// mode=1: Upload all files that do not exist on the server.
// mode=2: Upload newer or non-existant files.
// mode=3: Upload only newer files. If a file does not already exist on the server, it is not uploaded.
// mode=4: transfer missing files or files with size differences.
// mode=5: same as mode 4, but also newer files.

// This example will use mode 5 to upload missing, newer, or files with size differences.
int mode = 5;
// This example turns on recursion to synchronize the entire tree. 
// Recursion can be turned off to synchronize the files of a single directory.
