/** An abstraction of EPUB package.
  *
  * This interface must be implemented by the caller.
  *
  * There are 4 types of files that can be inserted into the package: XML, CSS, binary and text.
  * There is really not expected any difference in their handling, as just binary file would be
  * sufficient. The separate types exist partly to make an interface similar to @c
  * libodfgen::OdfDocumentHandler, partly for convenience (no need to convert, e.g., @c
  * librevenge::RVNGString to @c librevenge::RVNGBinaryData in the library itself), partly for
  * simplifying unit testing of the generators.
