% Planned out file comparison
% This function takes the src directory and dest directory and compares the
% contents bytes.  The backup function should already have been run.  What
% we want to achieve with this function is that nothing got missed
% Jamie

% loop through the src files and if a file from the src matches a file in
% the dest, then see if the bytes or size is equal.  If equal then
% everything is cool and we can move to the next file in src, if not equal
% then if the src is larger it should be moved over to dest, and if src
% size is less than the dest we ask what to do and give the option to cease
% and desist
