geteltorito can extract the initial/default boot image from CDs (and ISOs) that follow the El Torito specification for bootable CD-ROMs.

Image data is written to standard output by default and all other information is written to standard error.

CDEmu client is a simple command-line client for controlling CDEmu daemon.

It provides a way to perform the key tasks related to controlling the CDEmu daemon, such as loading and unloading devices, displaying devices' status and retrieving/setting devices' debug masks.

Cdparanoia retrieves audio tracks from CDDA capable CDROM drives. The data can be saved to a file or directed to standard output in WAV, AIFF, AIFF-C or raw format. Most ATAPI, SCSI and several proprietary CDROM drive makes are supported; cdparanoia can determine if the target drive is CDDA capable. In addition to simple reading, cdparanoia adds extra-robust data verification, synchronization, error handling and scratch reconstruction capability.

cdrecord converts a CD image in a ".bin / .cue" format (sometimes ".raw / .cue") to a set of .iso and .cdr tracks.

Optical media (CD,DVD,BD) keep their data only for a finite time (typically for many years). After that time, data loss develops slowly with read errors growing from the outer media region towards the inside.

Dvdisaster stores data on CD/DVD/BD (supported media) in a way that it is fully recoverable even after some read errors have developed. This enables you to rescue the complete data to a new medium.

Data loss is prevented by using error correcting codes. Error correction data is either added to the medium or kept in separate error correction files. Dvdisaster works at the image level so that the recovery does not depend on the file system of the medium. The maximum error correction capacity is user-selectable.

dvd+rw-tools, mostly known for its command growisofs, is a collection of DVD and Blu-ray Disc burning tools. It requires another program, such as mkisofs, genisoimage, or xorrisofs to create ISO 9660 images.

cd-discid is a command-line tool to retrieve CDDB discid information from an audio CD.

GNU ccd2cue is a preprocessor for CD burning software that allows the conversion of the proprietary CCD format to the CUE format, which is well-supported by free software. These files are commonly distributed with CD images and are used to describe how tracks are laid out on the image.

Libcddb is a C library to access data on a CDDB server (freedb.org). It allows you to:

1. search the database for possible CD matches;

2. retrieve detailed information about a specific CD;

3. submit new CD entries to the database.

Libcddb supports both the custom CDDB protocol and tunnelling the query and read operations over plain HTTP. It is also possible to use an HTTP proxy server. If you want to speed things up, you can make use of the built-in caching facility provided by the library.

Libburn is a library for reading and writing optical discs. Supported media are: CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD+R/DL, DVD-RW, DVD-R, DVD-R/DL, BD-R, and BD-RE.

abcde is a front-end command-line utility (actually, a shell script) that grabs tracks off a CD, encodes them to Ogg/Vorbis, MP3, FLAC, Ogg/Speex and/or MPP/MP+ (Musepack) format, and tags them, all in one go.

cdrtools is a collection of command line utilities to create CD's, DVD's or Blue Ray discs. The most important components are cdrecord, a burning program, cdda2wav, a CD audio ripper which uses libparanoia, and mkisofs, which can create various disc images.

This is a C version of the certdata2pem Python utility that was originally contributed to Debian.

mkcert is a simple tool for making locally-trusted development certificates. It requires no configuration.

The deSEC can be used to obtain certificates with certbot DNS ownership verification. With the help of this hook script, you can obtain your Let's Encrypt certificate using certbot with authorization provided by the DNS challenge mechanism, that is, you will not need a running web server or any port forwarding to your local machine.

This package provides a certificate store containing only the Let's Encrypt root and intermediate certificates. It is intended to be used within Guix.

mbake is a Makefile formatter and linter,which is configurable via a TOML file. It intelligently deals with .PHONY declarations and line continuations, and ensures consistent formatting and style for your Makefile.

This software is a set of testing tools for GNU Guile projects with SRFI 64-based test suites. It comes with a command-line interface to run test collections, and a library that includes a test runner and helpers for writing tests.

This package provides a simple and limited unit-test framework for C++.

snitch aims to be a simple, cheap, non-invasive, and user-friendly testing framework. The design philosophy is to keep the testing API lean, including only what is strictly necessary to present clear messages when a test fails.

Pytest is a testing tool that provides auto-discovery of test modules and functions, detailed info on failing assert statements, modular fixtures, and many external plugins.

Mock is a library for testing in Python. It allows you to replace parts of your system under test with mock objects and make assertions about how they have been used. This library is now part of Python (since Python 3.3), available via the unittest.mock module.

This Pytest plugin enables creating Pytest parametrize decorators from external files.

Rapidcheck is a property based testing framework for C++. It works by generating random data to try and find a case breaks your given pre-condition.
