-### Deprecated legacy method using loadRcppModules
-
-Prior to release 0.9.11, where `loadModule` was introduced,
-loading all functions and classes from a module
-into a package namespace was achieved using the `loadRcppModules` function
-within the `.onLoad` body.
-
-```{r, eval=FALSE}
-.onLoad <- function(libname, pkgname) {
-    loadRcppModules()
-}
-```
-
-This will look in the package's `DESCRIPTION` file for the `RcppModules`
-field, load each declared module and populate their contents into the
-package's namespace. For example, a package defining modules
-`yada`, `stdVector`, `NumEx` would have this declaration:
-
-```
-RcppModules: yada, stdVector, NumEx
-```
-
-The `loadRcppModules` function has a single argument `direct`
-with a default value of `TRUE`. With this default value, all content
-from the module is exposed directly in the package namespace. If set to
-`FALSE`, all content is exposed as components of the module.
-
-Note: This approach is **deprecated** as of Rcpp 0.12.5, and now triggers a
-warning message. Eventually this function will be withdrawn.
-
 ### Just expose the module
 
 Alternatively to exposing a module's content via `loadModule`,
