DjVuLibre is an implementation of DjVu, including viewers, browser plugins, decoders, simple encoders, and utilities.

didjvu uses the Gamera framework to separate the foreground and background layers of images, which can then be encoded into a DjVu file.

ocrodjvu is a wrapper for OCR systems, that allows you to perform OCR on DjVu files.

d-tools provides two useful tools for the D language: rdmd, which runs D source files as scripts, and dustmite, which reduces D code to a minimal test case.

d_demangle is a small utility that can be used to demangle D symbols. A shared library is also provided.

DMD is the reference compiler for the D programming language.

DUB is a package and build manager for applications and libraries written in the D programming language. It can automatically retrieve a project's dependencies and integrate them in the build process.

The design emphasis is on maximum simplicity for simple projects, while providing the opportunity to customize things when needed.

LDC is an LLVM compiler for the D programming language. It is based on the latest DMD compiler that was written in C and is used for bootstrapping more recent compilers written in D.

This package provides a DMD-like wrapper for the GNU D Compiler.

This package provides bindings to GTK+ for D.

Dnsmasq is a light-weight DNS forwarder and DHCP server. It is designed to provide DNS and, optionally, DHCP to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either on each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines.

YADIFA is an authoritative name server for the Domain Name System (DNS). It aims for both higher performance and a smaller memory footprint than other implementations, while remaining fully RFC-compliant. YADIFA supports dynamic record updates and the Domain Name System Security Extensions (DNSSEC).

NSD, short for Name Server Daemon, is an authoritative name server for the Domain Name System (DNS). It aims to be a fast and RFC-compliant nameserver.

NSD uses zone information compiled via zonec into a binary database file (nsd.db). This allows fast startup of the name service daemon and allows syntax-structural errors in zone files to be flagged at compile time, before being made available to NSD service itself. However, most traditional BIND-style zone files can be directly imported into NSD without modification.

The collection of programs and processes that make up NSD are designed so that the daemon itself runs as a non-privileged user and can be easily configured to run in a chroot jail, thus making any security flaws in NSD less likely to result in system-wide compromise.

dnscrypt-wrapper is a tool to expose a name server over the dnscrypt protocol. It can be used as an endpoint for the dnscrypt-proxy client to securely tunnel DNS requests between the two.

Unbound is a recursive-only caching DNS server which can perform DNSSEC validation of results. It implements only a minimal amount of authoritative service to prevent leakage to the root nameservers: forward lookups for localhost, reverse for 127.0.0.1 and ::1, and NXDOMAIN for zones served by AS112. Stub and forward zones are supported.

Knot Resolver is a caching full resolver implementation written in C and LuaJIT, both a resolver library and a daemon.

MaraDNS is a small and lightweight DNS server. MaraDNS consists of a UDP-only authoritative DNS server for hosting domains, and a UDP and TCP-capable recursive DNS server for finding domains on the internet.

SmartDNS is a DNS server that accepts DNS query requests from local clients, obtains DNS query results from multiple upstream DNS servers, and returns the fastest access results to clients.

hnsd is a host name resolver for the Handshake Naming System (HNS) peer-to-peer network.

This package contains a small DNS daemon especially made to handle queries of DNSBL, a simple way to publish IP addresses and/or (domain) names which are somehow notable. Such lists are frequently used to refuse e-mail service to clients known to send unwanted (spam) messages.

rbldnsd is not a general-purpose nameserver. It answers to a limited variety of queries. This makes it extremely fast---greatly outperforming both BIND and djbdns---whilst using relatively little memory.

This command line tool to update Cloudfare DNS records is useful for tasks such as updating dynamic DNS records or updating DNS records for the ACME DNS-01 protocol.

dnscrypt-proxy is a tool for securing communications between a client and a DNS resolver. It verifies that responses you get from a DNS provider was actually sent by that provider, and haven't been tampered with. For optimal performance it is recommended to use this as a forwarder for a caching DNS resolver such as dnsmasq, but it can also be used as a normal DNS "server". A list of public dnscrypt servers is included, and an up-to-date version is available at https://download.dnscrypt.org/dnscrypt-proxy/dnscrypt-resolvers.csv.

Knot DNS is an authoritative name server for the Domain Name System (DNS), designed to meet the needs of root and top-level domain (TLD) name servers. It is implemented as a threaded daemon and uses a number of programming techniques to improve speed. For example, the responder is completely lock-free, resulting in a very high response rate. Other features include automatic DNS Security Extensions (DNSSEC) signing, dynamic record synthesis, and on-the-fly re-configuration.

openresolv is an implementation of resolvconf, the middleman between the network configuration services and /etc/resolv.conf. resolvconf itself is just a script that stores, removes and lists a full resolv.conf generated for the interface. It then calls all the helper scripts it knows about so it can configure the real /etc/resolv.conf and optionally any local nameservers other than libc.
