# This tool checks for layering violations in the include/ directory.
|
|
# It checks that:
|
|
# - public includes don't end up depending on non-public /ext/ includes.
|
|
# - public includes don't end up depending on private src/ headers.
|
|
# - We use consistently <angle brackets> for other libraries.
