    Let me start by thanking you for working on replacing GNU utilities with
    higher quality and less restrictively licensed alternatives. I haven't
    had time to read over the code very thoroughly, but I have a few initial
    comments:
    - Padding gzip'd tar archives (with bsdtar czf) causes gzip to report
      "trailing garbage" and fail, and in turn this causes GNU tar to fail.
      BSD pax (-wzf) and GNU tar (czf) do not pad compressed archives.
    - I would prefer it if compression was done by opening a pipe to gzip/bzip2
      instead of using libz/libbz2. This would make things simpler, and make it
      easier to support compress(1).
    - I don't think the URL/libfetch support belongs in a library that deals
      with archives. Perhaps the interface could be changed so that the
      caller could pass a FILE * or a file descriptor instead of a filename.
    - Filenames are too long :-)

    Tim
