339 L<Path::Class:Dir> for the filesystem path to the git repository.
343 The contents of .git/description.
347 Owner of the files on the filesystem.
351 The L<DateTime> of the last modification of the repository. This will be C<undef> if the repository has never been used.
355 True if this is a bare git repository.
361 An array of the name and sha1 of all heads/tags in the repository.
365 Hashref of ArrayRefs for each reference.
370 =head2 head_hash ($head?)
372 Return the sha1 for HEAD, or any specified head.
374 =head2 get_object ($sha1)
376 Return an appropriate subclass of L<Gitalist::Git::Object> for the given sha1.
378 =head2 list_revs ($sha1, $count?, $skip?, \%search?, $file?)
380 Returns a list of revs for the given head ($sha1).
382 =head2 snapshot ($sha1, $format)
384 Generate an archived snapshot of the repository.
385 $sha1 should be a commit or tree.
386 Returns a filehandle to read from.
388 =head2 diff ($commit, $patch?, $parent?, $file?)
390 Generate a diff from a given L<Gitalist::Git::Object>.
392 =head2 reflog (@lorgargs)
394 Return a list of hashes representing each reflog entry.
396 FIXME Should this return objects?
