"""
|
|
Scan the `client/` directory, take all function definitions with `self: Client`
|
|
as the first parameter, and generate the corresponding `Client` methods to call
|
|
them, with matching signatures.
|
|
|
|
The documentation previously existing in the `Client` definitions is preserved.
|
|
|
|
Imports of new definitions and formatting must be added with other tools.
|
|
|
|
Properties and private methods can use a different parameter name than `self`
|
|
to avoid being included.
