[git at git.openembedded.org]

rpurdie pushed a commit to branch master
in repository openembedded-core.

commit 4eaf434f885afbda03fe67ab6e9ff291c7a9c77e
Author: Markus Lehtonen <markus.lehtonen at linux.intel.com>
AuthorDate: Wed May 11 16:19:06 2016 +0300

    oeqa.utils: add git module
    
    A new helper module for easier interaction with Git repositories.
    Provides GitRepo class that represents one local Git repository clone.
    The GitRepo class currently only has one method, run_cmd(), for running
    arbitrary git commands in the repository. More specialized methods for
    commonly used git operations can be added later.
