searching for a "structure viewer" tool

[Sergey Spiridonov <sena@hurd.homeunix.org>]

Hi all

I am looking for a tool which will allow to describe binary structure,
some thing like

byte 0-3: ascii string: name
byte 4-5: uint16 network order:  age
byte 6: bitfield: flags
....
and so on


Then it should take arbitrary binary file and display contents of the
file nicely according to the description.

If found such a tool exists for MS Windows [1]. I remember there was
similar for MS DOS. Is there something like that for the Debian GNU/Linux?
