yamllint checks YAML syntax, duplicate keys, indentation, trailing
spaces, line length, and other formatting issues.

Version 1.37.1 supports Slackware 15.0's Python 3.9. Newer yamllint
releases require Python 3.10 or later.

python3-setuptools-opt, python3-build, and python3-installer are needed
only to build the package. python3-pathspec is required at runtime.
PyYAML is included in Slackware.

Run "yamllint file.yaml" or "yamllint directory/" to check files. Add a
.yamllint file to a project for custom rules, or use
"yamllint -d relaxed" to select the built-in relaxed configuration.
No system configuration file is installed.
