-
-=head2 description
-
-The contents of .git/description.
-
-=head2 owner
-
-Owner of the files on the filesystem.
-
-=head2 last_change
-
-The L<DateTime> of the last modification of the repository. This will be C<undef> if the repository has never been used.
-
-=head2 is_bare
-
-True if this is a bare git repository.
-
-=head2 heads
-
-=head2 tags
-
-An array of the name and sha1 of all heads/tags in the repository.
-
-=head2 references
-
-Hashref of ArrayRefs for each reference.
-
-
-=head1 METHODS
-
-=head2 head_hash ($head?)
-
-Return the sha1 for HEAD, or any specified head.
-
-=head2 list_tree ($sha1?)
-
-Return an array of contents for a given tree.
-The tree is specified by sha1, and defaults to HEAD.
-Each item is a L<Gitalist::Git::Object>.
-
-=head2 get_object ($sha1)
-
-Return an appropriate subclass of L<Gitalist::Git::Object> for the given sha1.
-
-=head2 hash_by_path ($sha1, $path, $type?)
-
-Returns the sha1 for a given path, optionally limited by type.
-
-=head2 list_revs ($sha1, $count?, $skip?, \%search?, $file?)
-
-Returns a list of revs for the given head ($sha1).
-
-=head2 snapshot ($sha1, $format)
-
-Generate an archived snapshot of the repository.
-$sha1 should be a commit or tree.
-Returns a filehandle to read from.
-
-=head2 diff ($commit, $patch?, $parent?, $file?)
-
-Generate a diff from a given L<Gitalist::Git::Object>.
-
-=head2 reflog (@lorgargs)
-
-Return a list of hashes representing each reflog entry.
-
-FIXME Should this return objects?
