+
+// The following TSLint rules have been disabled:
+// unified-signatures: Because there is useful information in the argument names of the overloaded signatures
+
+// Convention:
+// Use 'union types' when:
+//  - parameter types have similar signature type (i.e. 'string | ReadonlyArray<string>')
+//  - parameter names have the same semantic meaning (i.e. ['command', 'commands'] , ['key', 'keys'])
+//    An example for not using 'union types' is the declaration of 'env' where `prefix` and `enable` parameters
+//    have different semantics. On the other hand, in the declaration of 'usage', a `command: string` parameter
+//    has the same semantic meaning with declaring an overload method by using `commands: ReadonlyArray<string>`,
+//    thus it's preferred to use `command: string | ReadonlyArray<string>`
+// Use parameterless declaration instead of declaring all parameters optional,
+// when all parameters are optional and more than one
+
+declare namespace yargs {
+    // The type parameter T is the expected shape of the parsed options.
+    // Arguments<T> is those options plus _ and $0, and an indexer falling
+    // back to unknown for unknown options.
