[PATCH 0/4] Allow contrib/ to use Git's Makefile for perl code

The very final goal is to be able to move painlessly (credential) code from git-remote-mediawiki to Git.pm, but then it's nice for the user to be able to say just "cd contrib/mw-to-git && make install" and let the Makefile set perl's library path just like other Git commands written in perl.

This series does this while trying to minimize code duplication, and to make it easy for future other tools in contrib to do the same.

Matthieu Moy (4):
  Makefile: extract perl-related rules to make them available from other
    dirs
  perl.mak: introduce $(GIT_ROOT_DIR) to allow inclusion from other
    directories
  Makefile: factor common configuration in git-default-config.mak
  git-remote-mediawiki: use Git's Makefile to build the script
