WHAT ARE TAGS?
% Use tags in your m-file, like:
[..some code..]
%! Info: The code is based on H.Foobar, 1984. "On how to implement the following lines properly"
% However, I adopted section 4 of this paper in the following way:
% [..more information..]
%/
[..some more code..]
[debug line] %! debug
[..some more code..]
%! ToDo: Following code should be vectorized:
[..code to be vectorized later..]
%/

FEATURES?
Files:
* Give the root directory for parsing tags [parseTags(dir)]
* Give a maximum depth for folders
* Setting an other file extension instead of ".m"

Tags:
* Change the tags, which are valid. Default ist the list: {COMMENT, INFO, TODO, DEBUG}.
* Change the tags, which are printed to the console. Probably, you just want the list of debug tags
* change the open ("%!") and close ("%/") characters for tags
* you don't have to close single lined tags

General:
* The output contains a link to the file, where the tag was found, thus you can directly open the file.

INSTALL?
Best place to put the files is probably [MATLAB-INSTALLATION]/toolbox/local. But you might choose any other folder and set up the paths (matlab function: pathtool), that MATLAB will find path tools.

MORE INFORMATION?
Try parseTags('demo') to have some more information. Have a look on the parsed files, to get an impression, how to use tags. Use help with parseTags, getFiles and getTags. For detailed description of the options.
