If `-f` is given, only the inside of the body part is generated such that it could be integrated
into a HTML document.
+`--line-id-prefix`
+: Prefix of the id of each line `<span>` element.
+
+ By default, each line is enclosed in its own `<span>` element with an `id` attribute made of the line number prefixed by `L` (e.g. `L1` for the first line).
+
+ This option changes the prefix used.
+ If an empty string is used, then the `<span>` are generated without `id` attributes.
+
+ This option is especially usuful with `--fragment` when more than one highlighted code is
+ included in the same HTML document.
+ Each fragment can thus be generated with its own distinct prefix, or the id can be disabled alltogether.

`--first-line`
