  Given an n-term L-infinity algebra L, we construct a Kan simplicial manifold
which we think of as the 'Lie n-group' integrating L. This extends work of
Getzler math.AT/0404003 . In the case of an ordinary Lie algebra, our
construction gives the simplicial classifying space of the corresponding simply
connect Lie group. In the case of the string Lie 2-algebra of Baez and Crans,
this recovers the model of the string group introduced in math.QA/0504123 .
