+/// It supports `lower_case`, `UPPER_CASE`, `camelBack` and `CamelCase` casing
+/// and tries to convert from one to another if a mismatch is detected.
+///
+/// It also supports a fixed prefix and suffix that will be prepended or
+/// appended to the identifiers, regardless of the casing.
+///
+/// Many configuration options are available, in order to be able to create
+/// different rules for different kind of identifier. In general, the
+/// rules are falling back to a more generic rule if the specific case is not
+/// configured.
