+The ``args`` property of ``llvm.core.Function`` objects yields
+``llvm.core.Argument`` objects. This allows for setting attributes for
+functions arguments. ``Argument`` objects cannot be constructed from
+user code, the only way to get a reference to these are from
+``Function`` objects.
+
+The method ``add_attribute`` and ``remove_attribute`` can be used to add
+or remove the following attributes:
+
+Value\| Equivalent LLVM Assembly Keyword \|
+-----\|----------------------------------\| ``ATTR_ZEXT``\ \|
+``zeroext`` \| ``ATTR_SEXT``\ \| ``signext`` \| ``ATTR_IN_REG``\ \|
+``inreg`` \| ``ATTR_BY_VAL``\ \| ``byval`` \| ``ATTR_STRUCT_RET``\ \|
+``sret`` \| ``ATTR_NO_ALIAS``\ \| ``noalias`` \| ``ATTR_NO_CAPTURE``\ \|
+``nocapture`` \| ``ATTR_NEST``\ \| ``nest`` \|
+
+These method work exactly like the `corresponding
+methods <functions.html#fnattr>`_ of the ``Function`` class above. Refer
+`LLVM docs <http://www.llvm.org/docs/LangRef.html#paramattrs>`_ for
+information on what each attribute means.
+
+The alignment of any argument can be set via the ``alignment`` property,
+to any power of 2.
