@1 Auto Delete deletes all files (in a specific directory) with dates older than the specified number of days. It can be useful if you have pages generated through user's input. It can be run manually from a browser, through telnet, or automatically using crontab. There are only two variables to edit - the directory, and the file age.
@1 Age Status Indicator for Files and Folders is a script that checks the age of files and folders, and shows "NEW" image indicators according to the age. If pointed to a folder, the script will scan through all the files in that folder for the newest file (sub-folders and files in sub-folders are omitted).
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.
serverizor allows you to take a normal command- based program, and run it as a tcp server in the background. This means that you can start up such programs once, and then connect to them with a command-line client, and run commands, disconnect, connect again from some other machine, etc. So, you can use it to boot up a large program such as emacs or lisp (in interpretor mode, not in editor/windowing mode) in the background, and then whenever you want to run emacs/lispy scripts, you could just run a serverizor client with a few commands. Therefore, the client and the server are the same program.
