minidjvu is a multipage DjVu encoder and single page encoder/decoder. It doesn't support colors or grayscales, just black and white.

pdf2djvu creates DjVu files from PDF files. It is able to extract:

• graphics,

• text layer,

• hyperlinks,

• document outline (bookmarks),

• metadata (including XMP metadata).

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

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

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.

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

DMD is the reference compiler for the D programming language.

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 bindings to GTK+ for D.

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.

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

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.

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.

This is the Public Suffix List maintained by Mozilla. A "public suffix" is one under which Internet users can (or historically could) directly register names in the Domain Name System (DNS). Some examples of public suffixes are .com, .co.uk and pvt.k12.ma.us. This is a list of all known public suffixes.

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

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

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.

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.

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.

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.

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.

libmicrodns provides a minimal implementation of a mDNS resolver as well as an announcer. mDNS (Multicast Domain Name System) is a zero-config service that allows one to resolve host names to IP addresses in local networks.

BIND implements the DNS protocols for the Internet. It is both a reference implementation of those protocols and production-grade software, suitable for use in high-volume and high-reliability applications.

The name stands for "Berkeley Internet Name Domain" because the software originated in the early 1980s at the University of California at Berkeley.
