minimize the amount of work necessary.  Unlike make, rdmd tracks dependencies

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.")

name server for the Domain Name System (@dfn{DNS}).  It aims to be a fast and
RFC-compliant nameserver.

NSD uses zone information compiled via @command{zonec} into a binary database
file (@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 @code{chroot} jail, thus making any security flaws in NSD less likely
to result in system-wide compromise.")
