# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Hostname may be an IP address or hostname:
hostname = "www.some-ssh-server.com"

# 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.
