  - Rewrite patch 01-spelling-error.
  - Adjust lintian overrides.
  - Install new files.

  - Add symlink from fusermount-glusterfs manpage to mount.glusterfs.
  - Move gsync-sync-gfid from /usr/share to /usr/lib.
  - Add benchmarking directory.
* Remove old versioned build dependencies and build depend on libglib2.0-dev.
