+### Freestanding
+
+`beman::freestanding::inplace_vector` implements a minimal freestanding version of the specification,
+which marks all potentially throwing functions as `= deleted`.
+This is useful for platforms without exception support, as it will generate a compile-time error
+instead of a potential runtime error when trying to use a throwing function.
+
+``` C++
+beman::inplace_vector<int, 1> iv;
+iv.resize(0); // OK
+iv.resize(10); // will throw or abort
+
+beman::freestanding::inplace_vector<int, 1> fs_iv;
+fs_iv.resize(0); // will generate a compile-time error
+fs_iv.resize(10); // will generate a compile-time error
+```
