## DESCRIPTION

*v.support* is used to set/update vector map metadata. While GRASS GIS typically generates these metadata entries automatically, *v.support* allows users to manually edit them when necessary.

## EXAMPLE

```
# update scale to 1:24000
v.support myvectmap scale=24000
# update organization
v.support myvectmap organization="OSGeo labs"
v.info myvectmap
```
