function makedir(varargin)

% makedir -- Make a new directory.
%  makedir('thePath') creates a new sub-directory named 'thePath'
%   (no embellishments), located within the current directory.
%   A dialog is invoked if manual intervention is needed.  No
%   action is taken if the desired directory already exists.
%   The "present-working-directory" itself remains the same.
%  makedir "p q r" assumes that the arguments represent one
%   path-name with single-blanks between components.
%  makedir p q r is the same as makedir "p q r".
