(X)MedCon can be used to convert between different file formats used in medical imaging. The supported formats are ACR-NEMA 2.0, Analyze (SPM), Concorde/μPET, DICOM 3.0, CTI ECAT 6/7, NIfTI-1, Interfile 3.3, PNG, and GIF87a/89a. This package includes a command-line utility (medcon) and a GTK+ based GUI application (xmedcon).

This package provides plugins to use PostgreSQL as the database backend of an Orthanc DICOM server instead of SQLite.

Orthanc is a standalone DICOM server with a RESTful API and plugin mechanism for extending its functionality.

This package provides plugins to use MySQL or MariaDB as the database backend of an Orthanc DICOM server instead of SQLite.

Mercury is a logic/functional programming language which combines the clarity and expressiveness of declarative programming with advanced static analysis and error detection features. Its highly optimized execution algorithm delivers efficiency far in excess of existing logic programming systems, and close to conventional programming systems. Mercury addresses the problems of large-scale program development, allowing modularity, separate compilation, and numerous optimization/time trade-offs.

NYACC is set of Guile modules for generating parsers and lexical analyzers. It provides sample parsers, pretty-printers using SXML trees as an intermediate representation, a decent C parser and an `FFI Helper' tool to help create Guile Scheme bindings for C-based libraries. It also provides (partially implemented) compilers based on these parsers to allow execution with Guile as extension languages.

GNU Mes--Maxwell Equations of Software--brings the Reduced Binary Seed bootstrap to Guix and aims to help create full source bootstrapping for GNU/Linux distributions. It consists of a mutual self-hosting Scheme interpreter in C and a Nyacc-based C compiler in Scheme and is compatible with Guile.

M2-Planet, the PLAtform NEutral Transpiler, when combined with mescc-tools, compiles a subset of the C language into working binaries with introspective steps in between. It is self-hosting and for bootstrapping it also has an implementation in the M1 macro assembly language. M2-Planet is built as Phase-5 of the full source bootstrapping process and is capable of building GNU Mes.

Mescc-tools is a collection of tools for use in a full source bootstrapping process. It consists of the M1 macro assembler, the hex2 linker, the blood-elf symbol table generator, the kaem shell, exec_enable and get_machine.

jj is a simple file-system-based Jabber client, inspired by ii IRC client. Interaction with jj is done by writing and reading files from the server directory which jj creates. It is perfect for bots and notifications.

Official fork of the C library implementation of the Tox encrypted messenger protocol.

Relays messages between different channels from various messaging networks and protocols. So far it supports mattermost, IRC, gitter, xmpp, slack, discord, telegram, rocketchat, twitch, ssh-chat, zulip, whatsapp, keybase, matrix, microsoft teams, nextcloud, mumble, vk and more with REST API. Mattermost is not required.

Toxic is a console-based instant messaging client, using c-toxcore and ncurses. It provides audio calls, sound and desktop notifications, and Python scripting support.

LibGadu is library for handling Gadu-Gadu instant messenger protocol. The library is written in C and aims to be operating system and environment independent.

Nheko want to provide a native desktop app for the Matrix protocol that feels more like a mainstream chat app and less like an IRC client.

Many matrix features are supported, including user registration, rooms, typing notification, emojis, E2E encryption, and voip calls.

This package provides Ejabberd -- Robust, Ubiquitous and Massively Scalable Messaging Platform. It supports XMPP, MQTT and SIP protocols.

This module implements support for a Encrypted Push Notifications, a custom extension to XEP-0357: Push Notifications.

Psi+ is a spin-off of Psi XMPP client. It is a powerful XMPP client designed for experienced users.

Telegram-purple is a plugin for Libpurple, the communication library used by the Pidgin instant messaging client, that adds support for the Telegram messenger.

This package is on ``life support'' until tdlib-purple is a full replacement.
