I've not gotten any response, so I've started trying to write the parser
in python and remember why I got stuck the first time I tried.

The first four bytes of the file are a string denoting type, the next
four is an integer.

Quite simply, how do I read the first four bytes into a string and the
next four into an integer in python? If I can do this I think the rest
is downhill.

The FileType supports a read, i.e. 'f.read([n])  Reads at most n bytes'
but how could this be used to read into python native types???
