I started to develop new tool SBDoc. This tool is like JavaDoc or JSDoc to create document HTML files from program source code. The current version's program ID is NPW862.
Now SBDoc has CUI (character user interface). So, to run it, import, run once (for compile) and type as follows from command prompt, while src and out are source and output folder names.
SBDoc src /O out
And SBDoc will create an HTML file index.html in the described output folder.
The source code of this program is also uploaded on GitHub.
