#  Connect to an SSH server:

#  Upload synchronization modes:
#  mode=0: Upload all files
#  mode=1: Upload all files that do not exist on the FTP server.
#  mode=2: Upload newer or non-existant files.
#  mode=3: Upload only newer files.  If a file does not already exist on the FTP 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.

#  Additional files and directores can be excluded by setting the SyncMustNotMatch property.
#  The SyncMustNotMatch patterns apply only to the final filename or directory part of a path.
#  If a directory matches, then it will not be traversed in a recursive traversal.
# 
scp.put_SyncMustNotMatch("*.o;*.obj;*.log; temp")

#  The SyncMustMatch property can be set to restrict the files uploaded to only those
#  matching at least one pattern in a set.
scp.put_SyncMustMatch("*.cpp; *.h")

#  Do the recursive sync to upload newer or non-existant files:
bRecurse = true
mode = 2
success = scp.SyncTreeUpload(localRoot,remoteRoot,mode,bRecurse)
if (success != true)
    print scp.lastErrorText() + "\n";
    exit

#  The files actually uploaded can be examined in the SyncedFiles property.
#  It is a string property that contains the relative path, one per line, of each
#  file uploaded.
