zip_file_add() adds a file to a zip
  archive, while zip_file_replace() replaces an existing
  file in a zip archive. The argument archive specifies
  the zip archive to which the file should be added. name
  is the file's name in the zip archive (for
  zip_file_add()), while index
  specifies which file should be replaced (for
  zip_file_replace()). The flags
  argument can be any combination of ZIP_FL_OVERWRITE
  with one of ZIP_FL_ENC_*:
ZIP_FL_OVERWRITEzip_file_add only.ZIP_FL_ENC_GUESSZIP_FL_ENC_UTF_8ZIP_FL_ENC_CP437NOTE:
    zip_source_free(3) should not
    be called on a source after it was used successfully
    in a zip_file_add or
    zip_file_replace call.
zip_file_add() returns the
  index of the new file in the archive, and
  zip_file_replace() returns 0. Otherwise, -1 is
  returned and the error code in archive is set to
  indicate the error.
