[GRASS-user] ps.map and vlabel - subheaders possible?

Hi list,
does anybody know whether it is possible to define subheaders for groups of
vector categories of the same vector? "Normal" labels of such a group should
only contain the range of the drawn categories - something like

LANDUSE (landuse@PERMANENT)
o forest
o urban area
o ...

This would be helpful for more complex legends...

Best,
Wolfgang

Not automatically, but you can always create a custom legend,
"Alternatively, the user can create a custom legend by using the
rectangle, point, and text instructions." (ps.map help page vlegend
instruction)

Do you know about the "label" instruction?

typical way using no subheaders, which each cat or SQL group labeled
independently:

vareas landuse
  where 'SQL statement 1'
  label 'legend text 1'
  end
vareas landuse
  where 'SQL statement 2'
  label 'legend text 2'
  end
vareas landuse
  where 'SQL statement 3'
  label 'legend text 3'
  end
