Query: Nilpotent pseudogroups of functions on an interval   A near-identity nilpotent pseudogroup of order m >= 1 is a family f_1, ...,
f_n: (-1,1) -> R of C^2 functions for which: |f_i - id|_{C^1} < epsilon for
some small positive real number epsilon < 1/10^{m+1} and commutators of the
functions f_i of order at least m equal the identity. We present a
classification of near-identity nilpotent pseudogroups: our results are similar
to those of Plante, Thurston, Farb and Franks for nilpotent groups. As an
application, we classify certain foliations of nilpotent manifolds.
