> Similarly to COMPRESS-390, there are requirements of the zip content to be mapped directly
into memory and therefore may require special alignment on the embedded files. E.g. libraries
may be aligned to page (4096-bytes) boundary, images on 4-bytes boundary etc. By alignment
it's meant the offset from the beginning of file where the actual data stream starts, not
the header.
> One of the cases was (still is?) Android APK for which zipalign utility was created.
> It would be useful if commons-compress ZipArchiveOutputStream supports something similar
directly in its API.
