c     ****************************************************************
c     * This package provides IO routines for trajectories. A file   *
c     * is characterised by the filename <filename> and the file     *
c     * identifier <fid>. Different modes <mode> are supported:      *
c     *     mode=1: ascii, sorted by trajectory;                     *
c     *     mode=2: ascii, sorted by time;                           *
c     *     mode=3: fortran (unformatted)                            * 
c     *     mode=4: IVE netcdf (for compatibiltzy reasons)           *
c     * A trajectory set is given as 3d array <tra(ntra,ntim,ncol)>  *
c     * where <ntra> is the number of trajectories, <ntim> the       *
c     * number of times of each trajectory and <ncol> the number of  *
c     * columns of the trajectory. The first 4 columns are: time,    *
c     * longitude, latitude, pressure. The other columns are traced  *
c     * fields. The complete list of all columns is given in the     *
c     * array <vars(ncol)>. Finally, the reference date is given in  *
c     * the array <time(6)=year,month,day,hour,time length of the    *
c     * trajectory (hour,min)>.                                      *
c     *                                                              *
