   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
           Default: raster

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

DESCRIPTION

       The t.unregister 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
