  - remove other crypto related "recommends"

  - Switch from Module::Install to ExtUtils::MakeMaker
  - avoids the hassle with Module::Install for Perl without "." in @INC
  - add some resources cf META.json

1.014  2016-12-18
  - Fix RT#119224: "Issue about Can't locate loadable object for module"
      drop "use" statements in PAR/Heavy.pm added in edf5f24d

  - Fix RT#119010: "Wrong license link"
      always refer to the included LICENSE file

1.013  2016-11-27
  - Fix a crucial typo, hopefully fixes RT#118981 "Tests fail (with PAR \ 
1.012?)"

  - Build t/hello.par at "make" time

1.012  2016-11-25
  - Guard against concurrent extraction attempts of zip into "inc"
  - use a file lock to protect the extraction of the complete zip into \ 
"inc"

  - _run_member_*(), _tempfile(), _dl_extract():
     make the "persistent" filename only visible when the file
     has been completely written

  - Make build and test work if @INC does not include "."

  - Upgrade to Module::Install 1.17
