=head1 NAME
ExtUtils::Builder::Action::Code - Action objects for perl code
=head1 VERSION
version 0.020
=head1 SYNOPSIS
my $action = ExtUtils::Builder::Action::Code->new(
code => 'Frob::nicate(@_)',
modules => ['Frob'],
message => 'frobnicateing foo',
);
$action->execute(target => 'bar');
say "Executed: ", join ' ', @$_, target => 'bar' for $action->to_command;
=head1 DESCRIPTION
This is a primitive action object wrapping a piece of perl code. The easiest way to use it is to execute it immediately. For more information on using actions, see L<ExtUtils::Builder::Action|ExtUtils::Builder::Action>. The core attributes are code and serialized, though only one of them must be given, both is strongly recommended.
=head1 ATTRIBUTES
=head2 code
This is a code-ref containing the action. On execution, it is passed the arguments of the execute method; when run as command it is passed @ARGV. In either case, C<arguments> is also passed. Of not given, it is C<eval>ed from C<serialized>.
=head2 modules
This is an optional list of modules that will be dynamically loaded before the action is run in any way. This attribute is optional.
