   Parameters:
       input=name
           Name of the input space time dataset

       file=name
           Input file with map names, one per line

       type=name
           Type of the input map
           Options: raster, vector, raster_3d

       maps=name[,name,...]
           Name(s) of existing raster, vector or raster3d map(s) to unregister

DESCRIPTION

       This  module  is  designed to unregister raster, 3D raster and vector map layers from space time datasets
       and the temporal database.

       Map layer that should be unregistered from the temporal database can be specified  as  a  list  of  comma
       separated  map  names or using a text file, that contains one map layer name per line. By default the map
       type that should be unregistered is set to raster. The optiontype must be used to specify  3D  raster  or
       vector map layer types.

INPUT FILE FORMAT

       Specification of map names:
       a1
       a2
       a3
       a4
       a5
       a6

   NOTE
       In  case the input option is used to specify a space time dataset the maps are only unregistered from the
       space time dataset, but not from the temporal database. The reason is that  maps  can  be  registered  in
       multiple  space  time  datasets  and  there  is  a  need  to unregister them from a specific STDS without
       affecting other STDS.

EXAMPLE

       In this example a precipitation map it is registered into temperature dataset, so the wrong map  will  be
       unregister.
       t.register -i type=raster input=tempmean_monthly@climate_2009_2012 \
           maps=2012_01_precip \
           start="2013-01-01" increment="1 month"
       # We unregister raster map 2012_01_precip from a space time dataset,
       # the raster maps are still present in the temporal database
       t.unregister type=raster input=tempmean_monthly@climate_2009_2012 maps=2012_01_precip
       # We unregister raster map 2012_01_precip from the temporal database, hence
       # the time stamps are removed
       t.unregister type=raster maps=2012_01_precip
