    longDescription = ''
      The XAR project aims to provide an easily extensible archive format.
              Important design decisions include an easily extensible XML table of
              contents for random access to archived files, storing the toc at the
              beginning of the archive to allow for efficient handling of streamed
              archives, the ability to handle files of arbitrarily large sizes, the
              ability to choose independent encodings for individual files in the
              archive, the ability to store checksums for individual files in both
              compressed and uncompressed form, and the ability to query the table
              of content's rich meta-data.
