-# $Conf{FtpShareName} = 'c'; # backup 'c' share
-# $Conf{FtpShareName} = ['c', 'd']; # backup 'c' and 'd' shares
+# This value must be specified in one of two ways: either as a
+# subdirectory of the 'share root' on the server, or as the absolute
+# path of the directory.
+#
+# In the following example, if the directory /home/username is the
+# root share of the ftp server with the given username, the following
+# two values will back up the same directory:
+#
+# $Conf{FtpShareName} = 'www'; # www directory
+# $Conf{FtpShareName} = '/home/username/www'; # same directory
+#
+# Path resolution is not supported; i.e.; you may not have an ftp
+# share path defined as '../otheruser' or '~/games'.
+#
+# Multiple shares may also be specified, as with other protocols:
+#
+# $Conf{FtpShareName} = [ 'www',
+# 'bin',
+# 'config' ];
+#
+# Note also that you can also use $Conf{BackupFilesOnly} to specify
+# a specific list of directories to backup. It's more efficient to
+# use this option instead of $Conf{FtpShareName} since a new tar is
+# run for each entry in $Conf{FtpShareName}.
