use command **obfuscate** to obfuscate scripts directly. For
complicated package, use Project to manage obfuscated scripts.
Project includes 2 files, one configure file and one project
capsule. Use manifest template string, same as MANIFEST.in of Python
Distutils, to specify the files to be obfuscated.
To create a project, use command **init**, use command **info** to
show project information. **config** to update project settings, and
**build** to obfuscate the scripts in the project.
Other commands, **benchmark** to metric performance, **hdinfo** to
show hardware information, so that command **licenses** can generate
license bind to fixed machine.
All the old commands **capsule**, **encrypt**, **license** are
deprecated, and will be removed from v4.
A new document [src/user-guide.md](src/user-guide.md) is written for this new version.
