 using `pub use submodule::x`, the items that are intended to be public. This
 way, the implementation details that drove the choice to use nested submodules
 do not affect the public API.
-
-Generally the Rust Guidelines for submodules are followed in *ring*. However,
-the Rust Guidelines (and rustc/cargo) require (by default) that when a module
-*x* has submodules, the module must be in a *x*/mod.rs. This would result in
-many files named mod.rs, which would make navigating through the source code
-more difficult and confusing. Instead, use `#[path = "x/x.rs"] pub mod x;` (all
-on one line, which is an exception to the rule that attributes should each be
-on their own line) so that every module's filename is unique. Example:
-```
-#[path = "good_example/good_example.rs"] pub mod good_example;
 ```
 
 Note that this is only necessary when the module has submodules.
