This program magnifies a screen region by an integer positive factor and draws the result on a window. It is useful as an accessibility tool, which works with every X Window System based GUI (depends only on libX11); or as an assistant for graphic designers, who need to select individual pixels.

Libbraille is a library to easily access Braille displays and terminals.

MouseLoupe is a kind of magnifying glass combined with the mouse pointer which allows an easy and pleasant web navigation.

BRLTTY is a background process (daemon) which provides access to the Linux/Unix console (when in text mode) for a blind person using a refreshable braille display. It drives the braille display, and provides complete screen review functionality. Some speech capability has also been incorporated.

This package provides command line utilities for programming PCsensor and Scythe foot switches. It works for both single pedal and three pedal devices.

Espeakup is a bridge between the speakup driver implemented in the Linux kernel and the espeak-ng text to speech synthesizer. In order for this package to work, you need to have the following kernel modules built:

• CONFIG_SPEAKUP=m

• CONFIG_SPEAKUP_SOFT=m

Florence is an extensible scalable virtual keyboard for X11. It is useful for people who can't use a real hardware keyboard (for example for people with disabilities), but you must be able to use a pointing device (as a mouse, a trackball, a touchscreen or opengazer).

Florence stays out of your way when you don't need it: it appears on the screen only when you need it. A timer-based auto-click input method is available to help to click.

GNU acct provides a means for system administrators to determine system usage patterns. It provides information on, for example, connections, programs executed, and system resources used.

Library and tools for manipulating access control lists.

This Python extension module manipulates the POSIX.1e ACLs available on many file systems. These allow more fine-grained access control than traditional user/group permissions.

Ada/Ed is a translator-interpreter for Ada 83. It's intended primarily as a teaching tool and lacks the capacity, performance, and robustness of other contemporary or modern-day Ada compilers.

Ada/Ed was the first Ada compiler to pass the ACVC version 1.7 but fails many newer tests and is not a validated Ada system. Being an interpreter, it does not implement most representation clauses, and thus does not support systems programming close to the machine level.

Detox is a program that renames files to make them easier to work with under Unix and related operating systems. Spaces and various other unsafe characters (such as "$") get replaced with "_". ISO 8859-1 (Latin-1) characters can be replaced as well, as can UTF-8 characters.

This package provides a Perl interface (Perl::Rename) as well as a command-line utility (rename) that can rename multiple files at once based on a Perl regular expression.

ngrep is like GNU grep applied to the network layer. It's a PCAP-based tool that allows you to specify an extended regular or hexadecimal expression to match against data payloads of packets. It understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw, across a wide variety of interface types, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

WakeLan broadcasts a properly formatted UDP packet across the local area network, which causes enabled computers to power on.

Shepherd-run is a script which assists in creating one-off shepherd services from the command line. It is meant to partially fill the void left by systemd-run, since GNU Guix uses GNU Shepherd as its system service manager.

ISC's Dynamic Host Configuration Protocol (DHCP) distribution provides a reference implementation of all aspects of DHCP, through a suite of DHCP tools: server, client, and relay agent.

This software is end-of-life! ISC does not intend to issue any further maintenance releases.

Fasd (pronounced similar to "fast") is a command-line productivity booster. Fasd offers quick access to files and directories for POSIX shells. It is inspired by tools like autojump, z, and v. Fasd keeps track of files and directories you have accessed so that you can quickly reference them in the command line.

fdupes is a program for identifying duplicate files residing within specified directories.

ClusterSSH controls a number of xterm windows via a single graphical console window to allow commands to be interactively run on multiple servers over ssh connections.

The GNU Shepherd is a daemon-managing daemon, meaning that it supervises the execution of system services, replacing similar functionality found in typical init systems. It provides dependency-handling through a convenient interface and is based on GNU Guile.

GNU pies is a program that supervises the invocation and execution of other programs. It reads the list of programs to be started from its configuration file, executes them, and then monitors their status, re-executing them as necessary.

This package provides a minimal seat management daemon whose task is to mediate access to shared devices, such as graphics and input, for applications that require it.

Spindle is a tool for improving the performance of dynamic library and Python loading in HPC environments.
