% ---------------- Packed file support ---------------- %
% A packed file is the concatenation of several file groups, each of which
% is the result of compressing several files concatenated together.
% The packed file begins with a procedure that creates an appropriate
% decoding filter for each file group, as follows:
% <group-subfile-filter> -proc- <group-decode-filter>
% Thus, accessing an individual file requires 4 parameters:
% the starting address and length of the outer compressed file,
% and the starting address and length of the inner file.

% Filters don't support setfileposition, so we must skip data
% by reading it into a buffer. We rely on the fact that
% save/restore don't affect file positions.
