-The macro `using_cvec()` must be instantiated in the global scope. `X` is a type tag name and
-will affect the names of all cvec types and methods. E.g. declaring `using_cvec(i, int);`, `X` should
-be replaced by `i` in all of the following documentation.
-
-`using_cvec_str()` is a shorthand for:
-```
-using_cvec(str, cstr, c_rawstr_compare, cstr_del, cstr_from, cstr_str, const char*)
 ```
+`X` should be replaced by the value of i_tag in all of the following documentation.
