+The code generally follows Google's Bash style [guide], with notable exceptions:
+
+- Indent with four spaces, no tabs. The `.editorconfig` file helps with this.
+- Pipeline and compounds (e.g. `|` or `&&`) end a line instead of beginning it.
+- Variables are brace delimited (`${var}`) only when needed, but always quoted.
+- Function namespacing is done with `.` instead of `::` (e.g. `module.func()`).
