 ## Directory and file conventions
 
 - Avoid general utility packages. Packages called "util" are suspect. Instead, derive a name that describes your desired function. For example, the utility functions dealing with waiting for operations are in the `wait` package and include functionality like `Poll`. The full name is `wait.Poll`.
 - All filenames should be lowercase.
 - All source files and directories should use underscores, not dashes.
   - Package directories should generally avoid using separators as much as possible. When package names are multiple words, they usually should be in nested subdirectories.
