/* append_archive - main loop for appending to a tar archive
*
* DESCRIPTION
*
* Append_archive reads an archive until the end of the archive is
* reached once the archive is reached, the buffers are reset and the
* create_archive function is called to handle the actual writing of
* the appended archive data. This is quite similar to the
* read_archive function, however, it does not do all the processing.
