-//! For development and running the tests a backend for `ndarray-linalg` must be chosen. Normally
-//! one would add those as dev dependencies (the features would then be unified with the regular
-//! dependencies). However, linking somehow fails when the non-dev `ndarra-linalg` dependency is
-//! missing (which is the case for the `*-nolinalg*` features of the ndarray backend). To fix that,
-//! the `_dev_linalg_*` features were introduced. When testing and developing with one of the
-//! ndarray features with linalg support on, the appropriate `_dev_linalg_*` feature must be turned
-//! on as well. Note that the version number in `_dev_linalg_*` is always one below the `ndarray`
-//! version. For instance, for ndarray 0.15, one would use the `_dev_linalg_0_14` feature.
