The best way to understand how to use Caring Caribou is to look at the help screen:

cc.py --help
caringcaribou --help

This will list all available modules at the bottom of the output. Help for specific modules works the same way. For example, the help screen for the `send` module is shown by running

cc.py send --help
caringcaribou send --help

The module help always includes some usage examples. If the module has multiple sub functions, these have similar help screens as well:

cc.py send message -h
cc.py send file -h
caringcaribou send message -h
caringcaribou send file -h

More detailed usage information is available [in the documentation on usage](documentation/howtouse.md).

## Features and Architecture
Caring Caribou is based on a main entry point, `cc.py`, which runs the show. This enables an easy drop-in architecture for new modules, which are located in the `caringcaribou/modules` folder.
Caring Caribou is based on a main entry point in `caringcaribou.py` which runs the show. This enables an easy drop-in architecture for new modules, which are located in the `caringcaribou/modules` folder.

The `caringcaribou/utils` folder contains various higher level CAN protocol implementations and shared functions, meant to be used by modules.

- Create a python file with a function `module_main(args)` (or copy the template) in the `caringcaribou/modules` directory.
- In `setup.py`, add an entry under `caringcaribou.modules`, referencing your new module like: `my_module = caringcaribou.modules.my_module`
- Run `python setup.py install`
- Verify that the module is available, should be listed in the output of `cc.py -h`
- Verify that the module is available, it should be listed in the output of `caringcaribou -h`

If your new module is located in `caringcaribou/modules/foo.py` you will run it with the command `cc.py foo`.
If your new module is located in `caringcaribou/modules/foo.py` you will run it with the command `caringcaribou foo`.
Additional arguments (if any) are passed as arguments to the `module_main` function.
