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

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

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

• graphics,

• text layer,

• hyperlinks,

• document outline (bookmarks),

• metadata (including XMP metadata).

This is a small tool to convert DjVu files to PDF 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.

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

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.

DMD is the reference compiler for the D programming language.

This package provides bindings to GTK+ for D.

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

LDNS aims to simplify DNS programming, it supports recent RFCs like the DNSSEC documents, and allows developers to easily create software conforming to current RFCs, and experimental software for current Internet Drafts. A secondary benefit of using ldns is speed; ldns is written in C it should be a lot faster than Perl.

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.

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.

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.

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-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.

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 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.

DNSSEC-Trigger enables your computer to use DNSSEC protection for the DNS traffic. It relies on the Unbound DNS resolver running locally on your system, which performs DNSSEC validation. It reconfigures Unbound in such a way that it will signal it to to use the DHCP obtained forwarders if possible, fallback to doing its own AUTH queries if that fails, and if that fails it will prompt the user with the option to go with insecure DNS only.

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.

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

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.
