SquashFS 4 (BE)

This document summarizes all (so far known) technical details about a non-standard SquashFS format (called AVM-BE below) used by AVM since Fritz!OS Labor 6.35.

PS. The Freetz developer team is deeply grateful to the IPPF user PeterPawn for analyzing the AVM-BE format and providing the initial implementation of the mk-/unsquashfs utilities supporting it.
