DESCRIPTION

44       v.build builds support files for  (binary)  GRASS  vector  data  files.
45       These  support  files supply topology and category information that are
46       needed by other GRASS modules.
47
48       GRASS is generating these support files  automatically,  only  in  rare
49       cases the user has to (re)build them.
50
51       Refer  to  Vector  data processing in GRASS GIS for more information on
52       GRASS GIS vector data model.
53

NOTES

55       v.build creates support files only for binary vector  maps  located  in
56       the  user's current mapset. If vector map is located in another mapset,
57       you need to specify this:
58
59
60       v.build map=geology@PERMANENT
61
62
63       In case of errors, the user can optionally generate an error vector map
64       containing the erroneous vectors for later inspection.
