+Built-in parsers
+----------------
+
+sbt comes with several built-in parsers defined in `sbt.complete.DefaultParsers <../../api/sbt/complete/DefaultParsers$.html>`_.
+Some commonly used built-in parsers are:
+
+ * `Space`, `NotSpace`, `OptSpace`, and `OptNotSpace` for parsing spaces or non-spaces, required or not.
+ * `StringBasic` for parsing text that may be quoted.
+ * `IntBasic` for parsing a signed Int value.
+ * `Digit` and `HexDigit` for parsing a single decimal or hexadecimal digit.
+ * `Bool` for parsing a `Boolean` value
+
+See the `DefaultParsers API <../../api/sbt/complete/DefaultParsers$.html>`_ for details.
