This package provides a generic tagging application for Django projects, which allows association of a number of tags with any Model instance and makes retrieval of tags simple.

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

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

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

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

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

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

• graphics,

• text layer,

• hyperlinks,

• document outline (bookmarks),

• metadata (including XMP metadata).

DjView is a standalone viewer for DjVu files.

Its features include navigating documents, zooming and panning page images, producing and displaying thumbnails, displaying document outlines, searching documents for particular words in the hidden text layer, copying hidden text to the clipboard, saving pages and documents as bundled or indirect multi-page files, and printing page and documents.

The viewer can simultaneously display several pages using a side-by-side or a continuous layout.

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.

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

DMD is the reference compiler for the D programming language.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.
