[GRASS-user] grass env

[maven apache]

It seems that the batch job is easy,however I still have some questions:
1) during my process the location and mapset maybe changed, can it be set in
the script file?
2) My application is to support multiple users, so each user should have a
gisrc file, can it be set before run the batch job?
