You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: activemq.rb
    path of file: ./repos/homebrew-core/Formula/a
    
    the code of the file until where you have to start completion: class Activemq < Formula
  desc "Apache ActiveMQ: powerful open source messaging server"
  homepage "https://activemq.apache.
    
  def install
    useless = OS.mac? ? "linux" : "{macosx,linux-x86-32}"
    buildpath.glob("bin/#{useless}*").map(&:rmtree)

    libexec.install buildpath.children
    wrapper_dir = OS.mac? ? "macosx" : "#{OS.kernel_name.downcase}-#{Hardware::CPU.arch}".tr("_", "-")
    libexec.glob("bin/#{wrapper_dir}/{wrapper,libwrapper.{so,jnilib}}").map(&:unlink)
    (bin/"activemq").write_env_script libexec/"bin/activemq", Language::Java.overridable_java_home_env

    wrapper = Formula["java-service-wrapper"].opt_libexec
    wrapper_dir = libexec/"bin"/wrapper_dir
    ln_sf wrapper/"bin/wrapper", wrapper_dir/"wrapper"
    libext = OS.mac? ? "jnilib" : "so"
    ln_sf wrapper/"lib/libwrapper.#{libext}", wrapper_dir/"libwrapper.#{libext}"
    ln_sf wrapper/"lib/wrapper.jar", wrapper_dir/"wrapper.jar"
