Description
function m2html(varargin)
%M2HTML - Documentation Generator for Matlab M-files and Toolboxes in HTML
% M2HTML by itself generates an HTML documentation of the Matlab M-files found
% in the direct subdirectories of the current directory. HTML files are
% written in a 'doc' directory (created if necessary). All the others options
% are set to default (in brackets in the following).
% M2HTML('PropertyName1',PropertyValue1,'PropertyName2',PropertyValue2,...)
% sets multiple option values. The list of option names and default values is:
% o mFiles - Cell array of strings or character array containing the
% list of M-files and/or directories of M-files for which an HTML
% documentation will be built (use relative paths without backtracking).
% Launch M2HTML one directory above the directory your wanting to
% generate documentation for [ <all direct subdirectories> ]
% o htmlDir - Top level directory for generated HTML files [ 'doc' ]
% o recursive - Process subdirectories recursively [ on | {off} ]
% o source - Include Matlab source code in the generated documentation
% [ {on} | off ]
% o download - Add a link to download each M-file separately [ on | {off} ]
% o syntaxHighlighting - Source Code Syntax Highlighting [ {on} | off ]
% o tabs - Replace '\t' (horizontal tab) in source code by n white space
% characters [ 0 ... {4} ... n ]
% o globalHypertextLinks - Hypertext links among separate Matlab
% directories [ on | {off} ]
% o todo - Create a TODO list in each directory summarizing all the
% '% TODO %' lines found in Matlab code [ on | {off}]
% o graph - Compute a dependency graph using GraphViz [ on | {off}]
% 'dot' required, see <http://www.graphviz.org/>
% o indexFile - Basename of the HTML index file [ 'index' ]
% o extension - Extension of generated HTML files [ '.html' ]
% o template - HTML template name to use [ {'blue'} | 'frame' | ... ]
% o search - Add a PHP search engine [ on | {off}] - beta version!
% o save - Save current state after M-files parsing in 'm2html.mat'
% in directory htmlDir [ on | {off}]
% o load - Load a previously saved '.mat' M2HTML state to generate HTML
% files once again with possibly other options [ <none> ]
% o verbose - Verbose mode [ {on} | off ]
%
% For more information, please read the M2HTML tutorial and FAQ at:
% <http://www.artefact.tk/software/matlab/m2html/>

% Examples:
% >> m2html('mfiles','matlab', 'htmldir','doc');
% >> m2html('mfiles',{'matlab/signal' 'matlab/image'}, 'htmldir','doc');
% >> m2html('mfiles','matlab', 'htmldir','doc', 'recursive','on');
% >> m2html('mfiles','mytoolbox', 'htmldir','doc', 'source','off');
