This package contains the command line utilities for the ALSA project.

The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.

The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform-specific implementations.

Bash is the shell, or command language interpreter, that will appear in the GNU operating system. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification.

Oracle Berkeley DB is a family of open source, embeddable databases that allows developers to incorporate within their applications a fast, scalable, transactional database engine with industrial grade reliability and availability.

The BLFS-Bootscripts package contains a set of scripts to start/stop additional services at bootup/shutdown.

Boron is an interpreted, prototype-based, scripting language similar to Rebol. The interpreter and datatype system is a C library useful for building domain specific languages embedded in C/C++ applications.

BZip2 is a freely available, patent free (see below), high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression.

OpenSSL no longer includes any root certificates. This package adds root certificates as provided by mozilla.org.

This library offers a visual captcha generation system for REBOL web applications. Its goal is to protect web forms from spam produced by automated bots, using a test that is supposed to be only solvable by a human being.

Cdrtools is a set of command line programs that allows to record CD/DVD/BluRay media. The suite includes the following programs:
    cdrecord - A CD/DVD/BD recording program
    readcd - A program to read CD/DVD/BD media with CD-clone features
    cdda2wav - The most evolved CD-audio extraction program with paranoia support
    mkisofs - A program to create hybrid ISO9660/JOLIET/HFS filesystes with optional Rock Ridge attributes
    isodebug - A program to print mkisofs debug information from media
    isodump - A program to dump ISO-9660 media
    isoinfo - A program to analyse/verify ISO/9660/Joliet/Rock-Ridge Filesystems
    isovfy - A program to verify the ISO-9660 structures
    rscsi - A Remote SCSI enabling daemon
Cdrtools is under constant free and open development since February 1996. The goal for cdrtools development is to permanently provide a free suite of programs for writing CD/DVD/BD media and succeeding similar products (like e.g. HD-DVD).

Cheyenne is a full-featured Apache-class web server implementation using 100% native REBOL. The project started just as a simple rewrite of the UniServe's HTTPd service to make it more flexible and ended as creating Cheyenne. Cheyenne is built on top of the UniServe async network framework, so it inherits the gains of asynchronous I/O and mono-process lightweight design.

The GNU Core Utilities are the basic file, shell and text manipulation utilities of the GNU operating system. These are the core utilities which are expected to exist on every operating system.

cURL groks URLs.

CURL is a command line tool for transferring files with URL syntax, supporting FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, FILE and LDAP. CURL supports SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, kerberos...), file transfer resume, proxy tunneling and a busload of other useful tricks.

The DejaVu fonts are a font family based on the Vera Fonts release 1.10. Its purpose is to provide a wider range of characters, while maintaining the original look and feel through the process of collaborative development.

The Ext2 Filesystem Utilities (e2fsprogs) contain all of the standard utilities for creating, fixing, configuring , and debugging ext2 filesystems. They also supports the ext3 and ext4 filesystems.

The GNU Find Utilities are the basic directory searching utilities of the GNU operating system. These programs are typically used in conjunction with other programs to provide modular and powerful directory search and file locating capabilities to other commands.

FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.

FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.

This project aims to provide a set of free outline (PostScript Type0, TrueType, OpenType...) fonts covering the ISO 10646/Unicode UCS (Universal Character Set).

FreeType 2 is a software font engine that is designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images). It can be used in graphics libraries, display servers, font conversion tools, text image generation tools, and many other products as well.

Ghostscript is a package of software that provides:
    - An interpreter for the PostScript (TM) language, with the ability to convert PostScript language files to many raster formats, view them on displays, and print them on printers that don't have PostScript language capability built in;
    - An interpreter for Portable Document Format (PDF) files, with the same abilities;
    - The ability to convert PostScript language files to PDF (with some limitations) and vice versa; and
    - A set of C procedures (the Ghostscript library) that implement the graphics and filtering (data compression / decompression / conversion) capabilities that appear as primitive operations in the PostScript language and in PDF.

Giflib is a library for reading and writing gif images. It is API and ABI compatible with libungif which was in wide use while the LZW compression algorithm was patented.

Provides data structure handling for C, portability wrappers and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system.

The grep command searches one or more input files for lines containing a match to a specified pattern. By default, grep prints the matching lines.

THE groff (GNU roff) software is a typesetting package which reads plain text mixed with formatting commands and produces formatted output.
