function [M,CM] = xwdread(fname,flag)
%XWDREAD Read a XWD (X window dump) file from disk.
%   Note: XWDREAD has been grandfathered; use IMREAD instead.
%
%   [X,MAP] = XWDREAD('filename') reads the file 'filename' and
%   returns the indexed image X and colormap MAP. 
%
%   XWDREAD will read XWDs in the following formats:
%           Zpixmaps with depth of 1 or 8 bits
%           XYbitmaps
%           XYpixmaps with depth of 1
