NAME  - Creates topology for GRASS vector map.


       vector, topology

SYNOPSIS help     map=name     [error=name]      [option=string[,string,...]]
       [--overwrite]  [--verbose]  [--quiet]

           Allow output files to overwrite existing files

           Verbose module output

           Quiet module output

           Name of input vector map

           Name for vector map where erroneous vector features are written to

           Build topology or dump topology or spatial index to stdout
           Options: build,dump,sdump,cdump
           Default: build
           build: build topology
           dump: write topology to stdout
           sdump: write spatial index to stdout
           cdump: write category index to stdout

DESCRIPTION builds support files for  (binary)  GRASS  vector  data  files.
       These  support  files supply topology and category information that are
       needed by other GRASS modules.

       GRASS is generating these support files  automatically,  only  in  rare
       cases the user has to (re)build them.

       Refer  to  Vector  data processing in GRASS GIS for more information on
       GRASS GIS vector data model.

NOTES creates support files only for binary vector  maps  located  in
       the  user's current mapset. If vector map is located in another mapset,
       you need to specify this: map=geology@PERMANENT

       In case of errors, the user can optionally generate an error vector map
       containing the erroneous vectors for later inspection.
