=head1 NAME
ExtUtils::Builder::BuildTools::FromPerl - compiler configuration, derived from perl's configuration
=head1 VERSION
version 0.035
=head1 SYNOPSIS
my $planner = ExtUtils::Builder::Planner->new;
$planner->load_extension('ExtUtils::Builder::BuildTools::FromPerl', 0.034,
config => $config,
);
my $foo_o = $planner->object_name('foo');
$planner->compile('foo.c', $foo_o, include_dirs => ['.']);
my $foo_exe = $planner->executable_name('foo');
$planner->link([ 'foo.o' ], $foo_exe, libraries => ['foo']);
my $plan = $planner->materialize;
$plan->run($foo_exe);
=head1 DESCRIPTION
This module is a L<ExtUtils::Builder::Planner::Extension|ExtUtils::Builder::Planner::Extension> that facilitates compiling object. It takes one named argument: C<config>, an L<ExtUtils::Config> (compatible) object.
=head1 METHODS
=head2 add_methods(%options)
This adds two delegate methods to the planner, C<compile> and C<link>. It takes named arguments that will be prefixed to the named arguments for all delegate calls. In practice, it's mainly useful with the C<config>, C<profile> and C<type> arguments.
If your C<$planner> has a C<config> delegate, that will be used as default value for C<config>.
This is usually not called directly, but through L<ExtUtils::Builder::Planner|ExtUtils::Builder::Planner>'s C<load_extension> method.
=head1 DELEGATES
It inherits the following delegates from L<ExtUtils::Builder::BuildTools::Base>.
