15. ? Tuesday, November 15, 2011
16. Makefile.PL Build.PL Tuesday, November 15, 2011
17. Problems with Makefile.PL/Build.PL Tuesday, November 15, 2011
18. Lots of boilerplate Tuesday, November 15, 2011
19. use  ExtUtils::MakeMaker; WriteMakefile(    NAME  =>  ‘MyModule’,    VERSION  =>  ‘1.22’,    PREREQ_PM  =>  {        ‘JSON’  =>  0,        ‘Hash::MultiValue’  =>  ‘0.11’,    }, ); Tuesday, November 15, 2011

22. dzil has no boilerplate ... but it’s not a distribution! Tuesday, November 15, 2011
23. Can have deps configure_requires, META.yml inc/Module/Install.pm Tuesday, November 15, 2011
24. Makefile.PL Build.PL Tuesday, November 15, 2011
25. configure build test install Tuesday, November 15, 2011
26. configure build test install ✔ Tuesday, November 15, 2011
27. My application is not meant to be installed! e.g. dotcloud push Tuesday, November 15, 2011
28. Great for dists. Not-so for apps. Tuesday, November 15, 2011
29. By the way... Tuesday, November 15, 2011
30. I <3 Module::Install’s DSL Tuesday, November 15, 2011
31. CPAN Meta Spec v2 Awesome stuff. Tuesday, November 15, 2011

33. Marrying them together? Tuesday, November 15, 2011
34. A Proposal Tuesday, November 15, 2011
35. cpanfile Tuesday, November 15, 2011
36. requires  ‘Plack’,  0.9980; requires  ‘Catalyst’,  ‘>=  5.8,  <  5.9’; conflicts  ‘MooseX::Foo’,  ‘<  0.10’; on  ‘test’  =>  sub  {        requires  ‘Test::More’,  0.80; }; on  ‘develop’  =>  sub  {        requires  ‘Devel::NYTProf’; }; Tuesday, November 15, 2011
37. inspired by: gemfile(5) Tuesday, November 15, 2011
38. Backward compatible to: Module::Install(::DSL) Tuesday, November 15, 2011
39. Convertible to: CPAN::Meta::Prereqs Tuesday, November 15, 2011
40. requires  ‘Plack’,  0.9980; requires  ‘Catalyst’,  ‘>=  5.8,  <  5.9’; conflicts  ‘MooseX::Foo’,  ‘<  0.10’; on  ‘test’  =>  sub  {        requires  ‘Test::More’,  0.80; }; on  ‘develop’  =>  sub  {        requires  ‘Devel::NYTProf’; }; Tuesday, November 15, 2011
41. CPAN::Meta::Prereqs-­‐>new({    runtime  =>  {        requires  =>  {            ‘Plack’  =>  0.9980,            ‘Catalyst’  =>  ‘>=  5.8,  <  5.9’,        },        conflicts  =>  {            ‘MooseX::Foo’  =>  ‘<  0.10’,        },    },    test  =>  {        requires  =>  {            ‘Test::More’  =>  0.80,        },    },    develop  =>  {        requires  =>  {            ‘Devel::NYTProf’  =>  0,        },    } }); Tuesday, November 15, 2011
42. Will be supported by: cpanm 1.6, carton 1.0 Tuesday, November 15, 2011
