Support for unpacking Stratus VOS EVF archives?

[vmlemon]

It could be interesting, to support unpacking Status VOS EVF archives (examples of such files, are available at ftp://ftp.stratus.com/vos/tools/, such as alf_wrappers.save.evf.gz), since the format seems fairly simple, and source code, for the codec is available from ftp://ftp.stratus.com/vos/utility/evf-2.0.tar.gz, for examining the algorithms involved. To my knowledge, no tool is available for dealing with these archives, on a standard UNIX OS.
