Autoconf offers the developer a robust set of M4 macros which expand into shell code to test the features of Unix-like systems and to adapt automatically their software package to these systems. The resulting shell scripts are self-contained and portable, freeing the user from needing to know anything about Autoconf or M4.

Autobuild is a package that processes build logs generated when building software. Autobuild is primarily focused on packages using Autoconf and Automake, but can be used with other build systems too. Autobuild generates an HTML summary file, containing links to each build log. The summary includes project name, version, build hostname, host type (cross compile aware), date of build, and indication of success or failure. The output is indexed in many ways to simplify browsing.

The `config.guess' script tries to guess a canonical system triple, and `config.sub' validates and canonicalizes. These are used as part of configuration in nearly all GNU packages (and many others).

GNU Libtool helps in the creation and use of shared libraries, by presenting a single consistent, portable interface that hides the usual complexity of working with shared libraries across platforms.

simavr is a new AVR simulator for GNU/Linux or any platform that uses avr-gcc. It uses avr-gcc's own register definition to simplify creating new targets for supported AVR devices. The core was made to be small and compact, and hackable so allow quick prototyping of an AVR project. The AVR core is now stable for use with parts with <= 128KB flash, and with preliminary support for the bigger parts. The simulator loads ELF files directly, and there is even a way to specify simulation parameterps directly in the emulated code using an .elf section. You can also load multipart HEX files.

The LUFA HID loader program communicates with the LUFA HID bootloader to upload new firmware.

Microscheme, or (ms) for short, is a functional programming language for the Arduino, and for Atmel 8-bit AVR microcontrollers in general. Microscheme is a subset of Scheme, in the sense that every valid (ms) program is also a valid Scheme program (with the exception of Arduino hardware-specific primitives). The (ms) compiler performs function inlining, and features an aggressive tree-shaker, eliminating unused top-level definitions. Microscheme has a robust Foreign Function Interface (FFI) meaning that C code may be invoked directly from (ms) programs.

UFA is a simple to use, lightweight framework which sits atop the hardware USB controller in specific AVR microcontroller models, and allows for the quick and easy creation of complex USB devices and hosts. This package contains the user-submitted projects and bootloaders for use with compatible microcontroller models, as well as the demos and the documentation.

Ksoloti is an environment for generating and processing digital audio. It can be a programmable virtual modular synthesizer, polysynth, drone box, sequencer, chord generator, multi effect, sample player, looper, granular sampler, MIDI generator/processor, CV or trigger generator, anything in between, and more.

The Ksoloti Core is a rework of the discontinued Axoloti Core board. In short, Ksoloti aims for maximum compatibility with the original Axoloti, but with some layout changes and added features.

This package provides the runtime.

This package provides the patcher application.

The Axoloti patcher offers a “patcher” environment similar to Pure Data for sketching digital audio algorithms. The patches run on a standalone powerful microcontroller board: Axoloti Core. This package provides the patcher application.

wimlib is a C library and set of command-line utilities for creating, modifying, extracting, and mounting archives in the Windows Imaging Format (WIM files). It can capture and apply WIMs directly from and to NTFS volumes using ntfs-3g, preserving NTFS-specific attributes.

With dirvish you can maintain a set of complete images of your file systems with unattended creation and expiration. A dirvish backup vault is like a time machine for your data.

Grsync is a simple graphical interface using GTK for the rsync command line program. It currently supports only a limited set of the most important rsync features, but can be used effectively for local directory synchronization.

Burp is a network backup and restore program. It attempts to reduce network traffic and the amount of space that is used by each backup.

Vorta is a graphical backup client based on the Borg backup tool. It supports the use of remote backup repositories. It can perform scheduled backups, and has a graphical tool for browsing and extracting the Borg archives.

borgmatic is simple, configuration-driven backup software for servers and workstations. Protect your files with client-side encryption. Backup your databases too. Monitor it all with integrated third-party services. borgmatic is powered by borg.

Hdup2 is a backup utility, its aim is to make backup really simple. The backup scheduling is done by means of a cron job. It supports an include/exclude mechanism, remote backups, encrypted backups and split backups (called chunks) to allow easy burning to CD/DVD.

The Restic REST server is a high performance HTTP server that implements restic's REST backend API. It provides a secure and efficient way to backup data remotely, using the restic backup client and a rest: URL.

Disarchive can disassemble software archives into data and metadata. The goal is to create a small amount of metadata that can be used to recreate a software archive bit-for-bit from the original files. For example, a software archive made using tar and Gzip will need to describe the order of files in the tarball and the compression parameters used by Gzip.

Par2cmdline uses Reed-Solomon error-correcting codes to generate and verify PAR2 recovery files. These files can be distributed alongside the source files or stored together with back-ups to protect against transmission errors or bit rot, the degradation of storage media over time. Unlike a simple checksum, PAR2 doesn't merely detect errors: as long as the damage isn't too extensive (and smaller than the size of the recovery file), it can even repair them.
