%TYPP list M-File of PRTools
%    TYPE foo.bar lists the ascii file called 'foo.bar'.
%
%    TYPE foo lists the ascii file called 'foo.m'. 
% 
%    If files called foo and foo.m both exist, then
%       TYPE foo lists the file 'foo', and
%       TYPE foo.m list the file 'foo.m'.
% 
%    TYPE FILENAME lists the contents of the file given a full pathname
%    or a MATLABPATH relative partial pathname (see PARTIALPATH).
% 
%    See also DBTYPE, WHICH, HELP, PARTIALPATH.
%
%    This routine is overloaded by PRTools replacing tabs by two spaces
