Buildable, Testable, Installable Git repo for Perl modules

tl;dr We might need a standard build file to build a module from Git repository, especially for the ones using Module::Install or dzil.

The problem

When an author of CPAN module uses an authoring tool that generates build files when shipping them to CPAN, the git repository usually doesn't have enough files to build, test and install the module.

For example, if dzil (Dist::Zilla) is used, the repository only conatains dist.ini and there's no Makefile.PL or Build.PL so standard CPAN installers or Continuous Integration tools don't know how to run tests on it.

How to extract a SSH private key from gpg-agent

Problem: Lost private key file ~/.ssh/id_rsa, but could connect to remote hosts via pubkey auth anyway: gpg-agent cached the private key. How to get the private key?

Solution: Use gpg-protect-tool to get the key (you need to know the passphrase of course):

gpgsm --call-protect-tool --p12-export ~/.gnupg/private-keys-v1.d/your-keyfile.key >key.p12

Now you have a PKCS12 file and you can extract the private key like this:
