'  Possible synchronization modes 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.

'  This example will download all files, but only those files having filenames
'  that match *.gif and *.eml

'  Imagine our remote directory tree has these files and directories:

'  	accentedLatin1.txt
'  	accentedUtf8.txt
'  	alice.key
'  	anter_cert.pem
'  	chiliPepper.gif
'  	helloWorld.pdf
'  	abc/chiliPepper.gif
'  	abc/ghk/
'  	data/chiliPepper.gif
'  	data/xyz/dkimHtmlBody.txt
'  	data/xyz/dkimVerifyTest.eml
'  	data/xyz/emailForCreateDsn.eml
'  	text/frenchUtf8.txt
'  	text/helloWorld.txt
'  	text/PolishEmailBody.txt
'  	text/something/

'  Indicate that we only want to create auto-create local directories (if needed)
'  for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
'  1, then the corresponding local directory is created for each remote directory
'  traversed regardless of whether files within are downloaded.
