52 v.proj allows a user to convert a vector map in a specified mapset of a
53 specified location (different from current) with projection of input
54 location to the vector map in a current mapset of current location with
55 projection of current location (both projections are defined by corre‐
56 sponding PROJ_INFO files).
57
59 If out is not specified it is set to be the same as input map name.
60 If dbase is not specified it is assumed to be the current database.
61 The user only has to specify dbase if the source location is stored in
62 another separate GRASS database.
63 If set is not specified, its name is assumed to be the same as the cur‐
64 rent mapset's name.
65
66 v.proj supports general datum transformations, making use of the PROJ.4
67 co-ordinate system translation library.
