* TODO [2015-01-10 Sab] cpansqliteutils: deps & rev_deps: optimize query, usually it takes several seconds for tens+ dependencies, which is too slow for my taste
* TODO [2015-01-09 Fri] cpansqliteutils: recursive/multi-level should be breadth-first and not depth-first

  otherwise the output is slightly weird:
  

      $ cpandb-cpanmeta deps Rinci -l2
      +---------+----------+
      | module  | version  |
      | DefHash | v1.0.6   |
      |   perl  | 5.010001 |
      +---------+----------+
  
  while we would normally want:
  

      $ cpandb-cpanmeta deps Rinci -l2
      +---------+----------+
      | module  | version  |
      | DefHash | v1.0.6   |
      | perl    | 5.010001 |
      +---------+----------+
  

* TODO [2015-01-08 Thu] cpansqliteutils: deps: numify/normalize version?
