    Hi Ji,
    Thanks a lot, you saved my day with this Caprine.
    Kind regards

  2. Hi Ji. I am a fan of all the developers that break down the walls of separation and let open -source bust right on through. The developers like you that make it possible for the Linux/Unix community to grow more and more everyday by creating the tools that allow us users, especially new Linux users to come on board and have business as usual. You answer the, “Will I be able to do this if I convert to Linux,” questions with a strong, “Hell yes!” You are the 5-star Generals in the Linux/Unix community takeover. Keep up the good…no…the exceptional work. You are the strength in the community
