DESCRIPTION

35       v.build  builds  GRASS  support  files  for  (binary) GRASS vector data
36       files.  These support files supply topology  and  category  information
37       that are needed by other GRASS programs.
38
39       GRASS  is  generating  these  support files automatically, only in rare
40       cases the user has to (re)build them.
41
42       Refer to Vector data processing in GRASS GIS for  more  information  on
43       Grass GIS vector data model.
44

NOTES

46       v.build  creates  support files only for binary vector files located in
47       the user's current mapset. If binary file is located in another mapset,
48       you need to specify this:
49
50
51       v.build map=geology@PERMANENT
52
53
54       In case of errors, the user can optionally generate an error vector map
55       containing the erroneous vectors for later inspection.
