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.
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.
Bandwidth Management Tools is a total bandwidth management solution for Linux and can be used for firewalling, traffic graphing, and shaping. It is not based on any currently-available bandwidth management software and supports packet queues, bursting, complex traffic flow hierarchies, flow groups, traffic logging, and a simple real-time monitoring front-end.
Bluefish is a programmer's Web development editor written using GTK, designed to save the experienced webmaster some keystrokes. It features a multiple file editor, multiple toolbars, custom menus, image and thumbnail dialogs, open from the Web, CSS dialogs, PHP, HTML, Java, C, and XML support, external program integration (tidy, weblint, make, javac), and lots of wizards.
CWXML is an high-performance, open-source C-language library for parsing and generating XML and BXML formats with a straightforward API. Initial testing indicates that it is 3 or more times faster than other popular libraries such as expat and libxml2 at parsing XML and much faster again with BXML, which is a straightforward, open, patent-unencumbered binary-encoding format for XML data that is a stand-alone work-alike drop-in replacement for an XML file that mirrors the XML markup structures in a way that is similar to the in-memory representations of many parser libraries.
