The Aardvark Shell Utils is a collection of three utilities designed to aid the user when working with shell scripts or from the command line. All three accept input on the command line or from standard input, and thus they can be piped with other commands. All commands come with their own man page. Included are realpath, filebase, and fileext.
AntiCutAndPaste is designed to search for text fragments that have been copied and pasted in programming language source code or plain text. It has been tested on sources from large C++, Pascal, Java, and C# (Mono) projects. The algorithms used are very fast and can handle up to three million C++ code lines in one minute. Minor modifications of code are ignored during the search. Reports are sorted conveniently by the total size of all similar fragments and there are many report customization options.
Aquamacs is a Mac-like version of the powerful Emacs text editor that runs as a standard OS X application. It features extensive customization that enables it to conform better with Apple's standard Human Interface Guidelines (HIG) than standard versions of the editor do. It provides a more Mac-like user experience than Carbon Emacs.
Aranha is a piece of software written to allow Web applications to be written more cleanly and more easily. It is a Local FastCGI Responder, although work is in progress to allow it to work as a FastCGI Authoriser and a FastCGI Filter. It is based on the programming language Lua, and contains many extensions to enable easy Web site development and maintenance.
Aspic is a program that generates line art images from a text description of a picture that contains commands such as "line", "box", "circle", and "arc". Aspic's concept is similar to the "pic" command. Output is either encapsulated PostScript, or Scalable Vector Graphics (SVG). Quite complex pictures can be constructed from Aspic's primitives, which include facilities for positioning text alongside graphics, and the use of colour.
Augeas is a configuration API and editing tool. It parses common configuration files like /etc/hosts or /etc/grub.conf in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native configuration files.
AutoGen is a tool designed for generating program files that contain repetitive text with varied substitutions. Its goal is to simplify the maintenance of programs that contain large amounts of repetitious text. This is especially valuable if there are several blocks of such text that must be kept synchronized. Output is specified with a Scheme-enhanced output template. Input, if required by your template, may come from AutoGen definitions, CGI data, or XML files.
