Demonstrates how to find out which files were downloaded in a SyncTreeDownload method call.

// Synchronize the remote directory tree rooted at "syncDownloadTest/xml"
// with the local directory tree rooted at "qa_output"
// 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.

remoteDir := 'syncDownloadTest';
localDir := 'qa_output';

// Possible modes that can be passed to the SyncTreeDownload method are:
// mode=0: Download all files
// mode=1: Download all files that do not exist on the local filesystem.
// mode=2: Download newer or non-existant files.
// mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server.
// mode=5: Download only missing files or files with size differences.
// mode=6: Same as mode 5, but also download newer files.
// mode=99: Do not download files, but instead delete remote files that do not exist locally.

// This example will use mode 6 to download missing, newer, or files with size differences.
mode := 6;
// This example will turn on recursion to synchronize the entire tree. 
// Recursion can be turned off to synchronize the files of a single directory.

// Local directories that were created will be listed with a trailing "/" char.
