first identifying line:

      ibr   :	  the index of the branch
      ntot  :	  the index of the point
      itp   :	  the type of point
      lab   :	  the label of the point
      nfpr  :	  the number of free parameters used in the computation
      isw   :	  the value of isw used in the computation
      ntpl  :	  the number of points in the time interval [0,1]
		  for which solution data are written
      nar   :	  the number of values written per point
		  (nar=ndim+1, since t and u(i), i=1,..,ndim are written)
      nrowpr:	  the number of lines printed following the identifying line
		  and before the next data set or the end of the file
		  (used for quickly skipping a data set when searching)
      ntst  :	  the number of time intervals used in the discretization
      ncol  :	  the number of collocation points used
      nparx :	  the dimension of the array par

following this are ntpl lines containing
      t u_1(t) u_2(t) ... u_ndim(t)

following this is a line containing the indices of the free parameters
      icp(i) for i=1,...,nfpr

followed by a line containing the parameter directions of the branch
      rl_dot(i) for i=1,...,nfpr

following this are ntpl lines each containing the directions of the mesh
      u_dot_1(t) u_dot_2(t) ... u_dot_ndim(t)

followed by
inally the parameter values 
      par(i) for i=1,...,nparx
