    - "Nothing to be done" message is output if everything is up-to-date
    - Download failures and cksum failures are handled differently

    - Fixes in error messages

  nih search|meta|info:
    - Option -p was added. With a help of it one may search in
      pkgsrc packages offline. Also see "nih refresh -p" and man page
