(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).

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.

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

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.

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.

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.

Libstrophe is a minimal XMPP library written in C. It has almost no external dependencies, only an XML parsing library (expat or libxml are both supported).

This module provides a way to configure a list of XMPP client apps recommended by the current server. This list is used by other modules such as mod_invites_page and mod_invites_register_web.

It also contains the logos of a number of popular XMPP clients, and serves them over HTTP for other modules to reference when serving web pages.

Profanity is a console based XMPP client written in C using ncurses and libmesode, inspired by Irssi.

GNU Freetalk is a command-line Jabber/XMPP chat client. It notably uses the Readline library to handle input, so it features convenient navigation of text as well as tab-completion of buddy names, commands and English words. It is also scriptable and extensible via Guile.

Loudmouth is a lightweight and easy-to-use C library for programming with the XMPP (formerly known as Jabber) protocol. It is designed to be easy to get started with and yet extensible to let you do anything the XMPP protocol allows.

OTR allows you to have private conversations over instant messaging by providing: (1) Encryption: No one else can read your instant messages. (2) Authentication: You are assured the correspondent is who you think it is. (3) Deniability: The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured the messages he sees are authentic and unmodified. (4) Perfect forward secrecy: If you lose control of your private keys, no previous conversation is compromised.

Purple-Mattermost is a plug-in for Purple, the instant messaging library used by Pidgin and Bitlbee, among others, to access Mattermost servers.

This module implements support for a group of push notification extensions by the Tigase team that allow a client to specify filters to be applied to push notifications. It is a custom extension to XEP-0357: Push Notifications.

Biboumi is a Free, Libre and Open Source XMPP gateway that connects to IRC servers and translates between the two protocols. Its goal is to let XMPP users take part in IRC discussions, using their favourite XMPP client.

This package provides Zulip's Flask server for running bots.
