classdef MCount < handle
%MCount counts the number of M-codes you have written
%
% MCount.lines(path) count the lines you have written under
%   directory filepath.
%
% MCount.reallines(path) count the lines you have written under
%   directory filepath, but omits the emtpy lines and comment lines.
%
% MCount.size(path) adds up the size of your m-files under directory
%   filepath
%
% All of them support multi-paths (in cells), for example,
% MCount.lines({'patha', 'pathb/pathc', 'filed'});
%
% My(zhang@zhiqiang.org) result: in recent 1 year, I wrote 19524 lines of
% M-codes totally, 12311 lines except for empty lines and comments lines,
% 603K in file size.
