+============================
+
+This check is similar to `-Wold-style-cast`, but it suggests automated fixes
+in some cases. The reported locations should not be different from the ones
+generated by `-Wold-style-cast`.
+
+C-style casts can perform a variety of different conversions (``const_cast``,
+``static_cast``, ``reinterpret_cast``, or a combination). This makes them
+dangerous as the intent is not clear, and they can silently perform unsafe
+conversions between incompatible types.
