=head1 NAME

Alien::Build::Plugin::Gather::IsolateDynamic - Plugin to gather dynamic libraries into a separate directory

=head1 VERSION

version 1.42

=head1 SYNOPSIS

 use alienfile;
 plugin 'Gather::IsolateDynamic';

=head1 DESCRIPTION

This plugin moves dynamic libraries from the C<lib> and C<bin> directories and puts them in
their own C<dynamic> directory.  This allows them to be used by FFI modules, but to be ignored
by XS modules.

This plugin provides the equivalent functionality of the C<alien_isolate_dynamic> attribute
from L<Alien::Base::ModuleBuild>.
