ARts 'aRts' is a framework for developing modular multimedia applications. The sound server, artsd, lets multiple applications cooperatively process and output sound and music. aRts provides its filter and synthesis capabilities to other applications using the multimedia communication protocol (MCOP). The package is also capable of modular realtime synthesis. It can create sounds & music (realtime midi synthesis) using small modules like oscillators for creating waveforms, various filters, mixers, faders, etc. As of Dec 02, 2004, development on this project has been discontinued.

AVFS A Virtual File System lets programs look inside archived or compressed files, or access remote files without recompiling the programs or changing the kernel. It currently supports floppies, tar and gzip files, zip, bzip2, ar and rar files, ftp sessions, http, webdav, rsh/rcp, ssh/scp. Quite a few other handlers are implemented with the Midnight Commander's external FS.

Aardvark Shellutils The Aardvark Shell Utils collection includes the following three utilities:

Realpath- implementation of the 'realpath' function for returning
the canonicalized absolute pathname of an input path. This
generates an absolute pathname with all symlinks resolved and all
'.' and '..' characters removed. Many commands do not work well
with relative paths or paths containing symlinks. Realpath
resolves these absolute paths.

Filebase- returns the base portion of a filename, that is the
filename with its extension (e.g. .txt) removed. It returns
everything preceeding the last period in the input string. The
period itself is not returned.

Fileext- returns the extension portion of a filename
(e.g. txt). It returns everything following the last period in the
input string. The period itself is not returned.

Aasm Aasm is an advanced assembler designed to support several target architectures and output file formats using plugins. It has been designed to be easily extended and, should be considered as a good alternative to monolithic assembler development for each new target CPUs and binary file formats.

AllPairs Pairwise (aka "all-pairs") test combinations generator written in Python. Allows one to create a set of tests using "pairwise combinations" method, reducing a number of combinations of variables into a lesser set that covers most situations.

Anjuta 'Anjuta' is a GNOME development IDE that can create GNOME/Gtk+ applications with glade or glade-gnome; it can also create generic applications. Current features include project management, application wizards, an on-board interactive debugger, and a source editor with source browsing and syntax highlighting.

AppTools The AppTools project includes a set of packages that Enthought has found useful in creating a number of applications. They implement functionality that is commonly needed by many applications

• enthought.appscripting: Framework for scripting applications.
• enthought.help: Provides a plugin for displaying documents and examples and running demos in Envisage Workbench applications.
• enthought.io: Provides an abstraction for files and folders in a file system.
• enthought.naming: Manages naming contexts, supporting non-string data types and scoped preferences.
• enthought.permissions: Supports limiting access to parts of an application unless the user is appropriately authorised (not full-blown security).
• enthought.persistence: Supports pickling the state of a Python object to a dictionary, which can then be flexibly applied in restoring the state of the object.
• enthought.preferences: Manages application preferences.
• enthought.resource: Manages application resources such as images and sounds.
• enthought.scripting: A framework for automatic recording of Python scripts.
• enthought.sweet_pickle: Handles class-level versioning, to support loading of saved data that exist over several generations of internal class structures.
• enthought.template: Supports creating templatizable object hierarchies.
• enthought.type_manager: Manages type extensions, including factories to generate adapters, and hooks for methods and functions.
• enthought.undo: Supports undoing and scripting application commands.

Arfg 'arfg,' originally intended to generate Fortran code, is a simple pipelined meta-language. Its power comes from the tools it employs: GNU m4 for macro expansion, a diversion filter for accumulation and re-location of text blocks, and the embedded Perl interpreter eperl.

AsmIDE This release includes a new debugger, source code generator, disassembler, updated reference tool, library expansion and numerous other changes.
AsmIDE is a collection of program to support assembler development on GNU/Linux. It runs in a terminal and the library supports terminal programs.

Atomthreads Atomthreads is a free, lightweight, portable, real-time scheduler for embedded systems. It is targeted at systems that need only a scheduler and the usual RTOS primitives. No file system, IP stack or device drivers are included, but developers can bolt on their own as required. Atomthreads will always be a small number of C files which are easy to port to any platforms that require threading by adding a simple architecture-specific file.

Authz-tools 'authz-tools' is a set of tools to manipulate authz files (as used by mod_authz_svn). It currently contains two utilities:

authz-tool -- extracts and modifies information in a
authz file from command line

authz-admin -- a cgi when you have numerous repositories served with
help of SVNParentPath directive (see mod_dav_svn
module documentation)

Autoproject autoproject interviews the user, then creates a source package for a new program which follows the GNU programming standards. The new package uses autoconf to configure itself, and automake to create the Makefile. `make distcheck' succeeds. . The idea is that you execute autoproject just once when you start a new project. It will ask a few questions, then create a new directory and populate it with standard files, customized for the new project. . Optionally, the new package will use a command line parser generator. Currently, autoproject supports two parser generators: clig by Harald Kirsch (kirschh@lionbioscience.com) (see http://wsd.iitb.fhg.de/~kir/clighome/), and autogen by Bruce Korb (korbb@datadesign.com) (see ftp://autogen.sourceforge.net/autoopts).

BIEW BIEW- is multiplatform portable viewer of binary files with built-in editor in binary, hexadecimal and disassembler modes. It uses native Intel syntax for disassemble. Highlight AVR/Java/Athlon64/Pentium 4/K7-Athlon disassembler, russian codepages convertor, full preview of formats - MZ, NE, PE, NLM, coff32, elf partial - a.out, LE, LX, PharLap; code navigator and more over.

BIF Build it Fast (BIF) is a PHP Framework. It contains several classes that help you develop complex Web applications in a short amount of time. It brings the concept of the 'widget' to Web development. It features Cascade Skins and transparent session management.

BYLD 'Byld' helps you build a GNU/Linux distribution on a single floppy disk to use as you want (net client, rescue disk...). It is not a complete distribution: it was made only to build a mini distribution on a floppy. You can use it however you want as is (follow quick installation instruction below) but its best use is to configure and build your own floppy distribution.

Bbe bbe is a sed-like editor for binary files. bbe performs basic byte operations on blocks of input stream. bbe is command line tools developed in GNU/Linux environment.Features include:

• Non-interactive command-line tool.
• Reads input stream in arbitrary blocks, not as lines as sed.
• Input blocks can be defined as offset and length, just length, or using start and stop strings.
• Basic commands: insert, delete, change, replace and convert data.
• Commands can be given in command line or read from script-file.
• Blocks can be written either to standard output or file.

Binfind 'binfind' searches files for a byte sequence. The pattern can be given on the command line in ASCII or hex, read from a file, or a combination of the above. It uses the Boyer-Moore algorithm and can search large files without using a lot of memory. For each occurrence of the pattern, 'binfind' prints a line containing the offset of the occurrence in the searched file. If the user specifies more than one file, binfind prints the filename and a colon before the offset.

Binutils Includes tools capable of creating and managing binary program files, including handling object files, libraries, profile data, and assembly source code.

Bison Bison is a general-purpose parser generator that converts an annotated context-free grammar into an LALR(1) or GLR parser for that grammar. Once you are proficient with Bison, you can use it to develop a wide range of language parsers, from those used in simple desk calculators to complex programming languages. Bison is upward compatible with Yacc: all properly-written Yacc grammars ought to work with Bison with no change. Anyone familiar with Yacc should be able to use Bison with little trouble. You need to be fluent in C or C++ programming in order to use Bison.

Bochstools Bochs-Tools is a collection of scripts and programs to be used together with the Bochs emulator. The main goal is to provide a more Unix-like interface to the emulator and to enable access to Bochs disk images from outside of Bochs. This project makes it very simple to copy an existing OS installation to a Bochs image.
