+    Format tokens with ANSI color sequences, for output in a text console.
+    Color sequences are terminated at newlines, so that paging the output
+    works correctly.
+
+    The `get_style_defs()` method doesn't do anything special since there is
+    no support for common styles.
+
+    Options accepted:
+
+    `bg`
+        Set to ``"light"`` or ``"dark"`` depending on the terminal's background
+        (default: ``"light"``).
+
+    `colorscheme`
+        A dictionary mapping token types to (lightbg, darkbg) color names or
+        ``None`` (default: ``None`` = use builtin colorscheme).
+
+    `linenos`
+        Set to ``True`` to have line numbers on the terminal output as well
+        (default: ``False`` = no line numbers).
