BUNCHO

1. The Buncho Java library currently provides very simple support for feature flags.
2. Just implement the 'FeatureFlags' interface and you're good to go.
3. It has 2 default methods that might do everything you need.
4. If not, then override them to do what you want.
5. There are 2 ways to set a feature flag:
   1. Create a file named $baseDir/$featureName_[true, false]
   2. Set a boolean system property named buncho.$featureName=[true, false]
6. The default baseDir for files is ~/.buncho
7. The file approach takes precedence over the system property approach, as it is intended for emergency changes without restarting the JVM.
8. Examples:
   1. ~/.buncho/awesomeFeature_true
   2. -Dbuncho.awesomeFeature=true
9. I'm using Java 21, but Buncho will probably work with Java 8.
