Openmolar is a dental practice management suite. Its functionality includes appointments, patient records, treatment planning, billing etc. It is a full featured, reliable and thoroughly tested application and has been translated into many languages.

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.

(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 GNUHealth Personal Health Record application for desktop and mobile devices that integrates with the GNU Health Federation.

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.

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.

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.

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.

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.

This module adds the ability to set vCard for MUC rooms. One of the most common use cases is to define avatars for MUC rooms.

This is a client library for libsignal-protocol-c. It implements the necessary interfaces using libgcrypt and sqlite.

This module implements support for sending messages in a MUC to affiliated users who are not in the room. This is a custom extension by Tigase to allow push notifications from MUCs to users who are not currently connected.

This package contains Zulip's official terminal client.

Plugin for libpurple to allow sending SMS using ModemManager.

Ytalk is a replacement for the BSD talk program. Its main advantage is the ability to communicate with any arbitrary number of users at once. It supports both talk protocols ("talk" and "ntalk") and can communicate with several different talk daemons at the same time.

Libircclient is a library which implements the client IRC protocol. It is designed to be small, fast, portable and compatible with the RFC standards as well as non-standard but popular features. It can be used for building the IRC clients and bots.

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.

Dino is a chat client for the desktop. It focuses on providing a minimal yet reliable Jabber/XMPP experience and having encryption enabled by default.
