"""Script to generate an include file that can be passed to ktfmt.py.
|
|
|
|
The include file is generated from one or more folders containing one or more
|
|
Kotlin files. The generated include file will exclude all Kotlin files that
|
|
currently don't follow ktfmt format. This way, we can easily start formatting
|
|
all new files in a project/directory.
