=head1 DESCRIPTION
This utility recursively searches in a root directory (which may be the current working directory or - if it has been set - the directory given by the C<GIT_DIR> environment variable) for all git repositories, sort this list by the repository path, C<chdir> into each of them, and executes the specified git command.
+For efficiency reasons, repositories located inside another repository won't be searched for.
+
Moreover, those formats are substituted in the arguments before running the command :
