@ (monkey-tail) is a simple collection of simple commands. Built-in commands include listing of memory usage and open files for a process (by name or PID), running processes detached from a terminal, and running a program only once. @ can merge external pieces of code into itself to provide extra commands. Additionally, these "externals" can then be updated from their source. Currently there are externals available for extracting archive files (including nested archives), setting the GNOME desktop wallpaper image, and for replicating @ to another host via SSH. Externals can easily be written, as they are simply collections of Bash functions. It is completely self contained and self modifying, and is implemented in a single file.
@-Tension CMS is a content management system which features XHTML strict compliance, a WYSIWYG HTML editor, complete accessibility (WAI compliance), flexible user and rights management, in-place authoring/administration via a Web browser, comprehensive built-in access statistics, and human-readable URLs.
@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).
@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.
