smartupload is another tool for uploading a Web-tree via FTP. The thing that sets smartupload apart from other upload tools is the way it selects files that need to be uploaded. Starting with a user-specified .html it recursively parses the file and its children in order to create a list of all files that are referenced. The resultant list is then searched for files that have changed since the last upload. Only these files will be uploaded. This means that additional files that are not part of your Web-tree (eg. maintenance files or other stuff you need in your local Web directory) will not considered for upload.
