    This plugin implements the ``kas for-all-repos`` command.

    When this command is executed, kas will checkout the repositories listed
    in the chosen config file and then execute a specified command in each
    repository. It can be used to query the repository status, automate
    actions such as archiving the layers used in a build or to execute any
    other required commands.

    For example, to print the commit hashes used by each repository used in
    the file ``kas-project.yml`` (assuming they are all git repositories) you
    could run::

        kas for-all-repos kas-project.yml 'git rev-parse HEAD'
