=head1 DESCRIPTION

This module extends an L<IO::Async::Loop> to use the system's name resolver
functions asynchronously. It provides a number of named resolvers, each one
providing an asynchronous wrapper around a single resolver function.

Because the system may not provide asynchronous versions of its resolver
functions, this class is implemented using a L<IO::Async::Function> object
that wraps the normal (blocking) functions. In this case, name resolutions
will be performed asynchronously from the rest of the program, but will likely
be done by a single background worker process, so will be processed in the
order they were requested; a single slow lookup will hold up the queue of
other requests behind it. To mitigate this, multiple worker processes can be
used; see the C<workers> argument to the constructor.

The C<idle_timeout> parameter for the underlying L<IO::Async::Function> object
is set to a default of 30 seconds, and C<min_workers> is set to 0. This
ensures that there are no spare processes sitting idle during the common case
of no outstanding requests.

=item General Usage (L<Module::Build>)

This is the document you are currently reading. It describes basic
usage and background information.  Its main purpose is to assist the
user who wants to learn how to invoke and control C<Module::Build>
scripts at the command line.

=item Authoring Reference (L<Module::Build::Authoring>)

This document describes the structure and organization of
C<Module::Build>, and the relevant concepts needed by authors who are
writing F<Build.PL> scripts for a distribution or controlling
C<Module::Build> processes programmatically.
