This is an example usage of 'ftp_sync'. 
Usually, you start editing files on Windows boxes by double-cliciking them.
Run this script, and the files will be synchronized with the master file
on a remote FTP server *before* and *after* invoking the default editor.

The default editor for the given application is read from the registry.

Usage:

    sync_citydesk.rb   "C:\My Files\my_proj.cty"
