SYNOPSIS
adig [@server] [-c class] [-p port#] [-q name] [-t type] [-x addr]
[name] [type] [class] [queryopt...]
DESCRIPTION
Send queries to DNS servers about name and print received information,
where name is a valid DNS name (e.g. www.example.com, 1.2.3.10.in-
addr.arpa).

It is possible to specify default arguments for adig via
${XDG_CONFIG_HOME}/adigrc.
