Changes (by rgommers):

  * status:  new => closed
  * resolution:  => fixed


Comment:

 Docs have improved a lot and seem to contain all Pauli's comments, for
 parameter s it now says:

 Positive smoothing factor used to choose the number of knots. Number of
 knots will be increased until the smoothing condition is satisfied:
 {{{
     sum((w[i]*(y[i]-s(x[i])))**2,axis=0) <= s
 }}}
 If None (default), s=len(w) which should be a good value if 1/w[i] is an
 estimate of the standard deviation of y[i]. If 0, spline will interpolate
 through all data points.
