+#' sparsevctrs options
+#' 
+#' These options can be set with `options()`.
+#' 
+#' ## sparsevctrs.verbose_materialize
+#' 
+#' This option is meant to be used as a diagnostic tool. Materialization of
+#' sparse vectors are done silently by default. This can make it hard to 
+#' determine if your code is doing what you want. 
+#' 
+#' Setting `sparsevctrs.verbose_materialize` is a way to alert when 
+#' materialization occurs. Note that only the first materialization is counted
+#' for the options below, as the materialized vector is cached.
+#' 
+#' Setting `sparsevctrs.verbose_materialize = 1` or 
+#' `sparsevctrs.verbose_materialize = TRUE` will result in a message being 
+#' emitted each time a sparse vector is materialized.
+#' 
+#' Setting `sparsevctrs.verbose_materialize = 2` will result in a warning being
+#' thrown each time a sparse vector is materialized.
+#'
+#' Setting `sparsevctrs.verbose_materialize = 3` will result in an error being
+#' thrown each time a sparse vector is materialized.
