   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
