    Autoconf is a tool for producing configure scripts for building, installing and packaging software. These scripts can adapt the packages to USS without manual user intervention. Autoconf is comonly used in conjunction with Make and other build automation tools.


    Automake is a programming tool to automate parts of the compilation process, easing common compilation problems such as identifying dependencies. Automake automatically generates GNU compliant files.

    Bash 4.2.53

    Bash is an sh-compatible shell providing users a command-line interpreter that provides a traditional interface via text window and a script execution capability. It is the default shell on Linux and Mac OS X.

    Bison 2.3

    Bison is a programming utility for creating parsers. It’s commonly used in both build automation and build automation generation, and converts annotated context-free grammar into a C, C++, or Java parser. Bison is used by PHP, Bash, Ruby, and many other tools.

    bzip2 1.0.6

    bzip2 is a data compressor that compresses single files (it is not a file archiver). It typically compresses files to within 10% to 15% of the best available techniques of statistical compressors, while being around twice as fast at compression and six times faster at decompression. This version of bzip2 was not written to exploit z Systems architecture; gzip may work best for these needs.

    cURL 7.42.1

    cURL is an open source tool that can transfer data to and from servers by using one of the supported protocols (HTTP, HTTPS, FTP, FTPS, TFTP, DICT, TELNET, LDAP, or FILE). This tool can work without user interaction. cURL functionality includes proxy support, user authentication, FTP upload, HTTP post, SSL connections, cookies, file transfer, resume, and more.

    CVS 1.11.23

    CVS is a version control system for managing source code files and modifications in a group development environment. It allows developers to write, share, reuse, branch, and merge code in a team environment while ensuring source code integrity.

    Diffutils 3.3

    Diffutils is a package of several programs intended to find differences between files. The diff command, for example, shows exact line differences between two files.

    Findutils 4.4.2

    Findutils is a package of utilities (find, locate, updatedb, and xargs) for searching files and directories.

    Groff 1.20.1

    groff is a typesetting system that reads plain text with in-line formatting commands to produce formatted output in PostScript or PDF, html, or ASCII/UTF8. Both primitive commands and macros can be used to format text.

    Gzip 1.6

    Gzip is a popular data compression/decompression program (our ported tools have been compressed using this utility). This version of Gzip has also been modified to exploit z/OS EDC compression hardware, if present on your system.

    libssh2 1.4.3

    libssh2 is a software library that allows developers to use the SSH-2 network protocol in an easy-to-use self-contained package. This package only contains LIBSSH2 libraries intended for use by other programs or utilities.

    m4 1.4.15

    M4 is a general-purpose macro processor. Most users require M4 simply as a dependency of Autoconf or Bison, although the language is used in other contexts such as text template re-use, text editing and text-processing applications.

    Make 4.0

    Make controls the generation of program executables and other non-source files from the program's source files. Make allows users to build, install and update packages without knowing the process details.

    Midnight Commander 4.6.1

    Midnight Commander is an open source clone of Norton Commander, a feature-rich full-screen text mode application that allows users to copy, move, and delete files and whole directory trees, as well as search for files and run commands in a subshell.

    Mktemp 1.7

    The mktemp utility takes a given filename template and overwrites a portion of it to create a unique filename. Mktemp also manages the creation of temporary files and directories that allow the user to avoid the cleaning up files that are not needed permanently.

    NEdit 5.5

    NEdit, the Nirvana text editor, is a text and source code editor extensible through a C-like macro language, and featuring automatic indentation and syntax highlighting for a wide variety of computer languages.

    Perl 5.22.0

    Perl is a general-purpose, interpreted, dynamic programming language. This port offers enhancements over other versions of Perl; it’s preconfigured and precompiled, designed to address the ASCII/EBCDIC conversion, and provides Unicode support.

    PHP 5.4.4

    PHP is a server-side scripting language, offering a simple and universal solution for easy-to-program dynamic Web pages. Programmers can embed PHP statements directly into HTML pages.

    Pkg-Config 0.28

    pkg-Config is a programming tool that assists with compiling applications and libraries. It helps you insert the correct compiler options on the command line without the need of hard coding values on where to find glib (or other libraries).

    Python 2.7.6

    Python is a general-purpose, high-level programming language. Python is an interpretive language, and allows users to get their programs working quickly, without a large learning curve.

    Sed 4.2.2

    sudo 1.8.6p3

    sudo is a command-line utility that allows admins to delegate authority, giving certain users the ability to run commands as a super-user or another user, while providing an audit trail of the commands and their arguments.

    TCL 8.5.11
