First join AuthzsvnaccessFile SvnAccessFile to Apache's configuration file.
Then add the following statement in SVNAccessFile:
# [groups]
Developers = User1, User2, User3, User4
DOCS = User5, user6, user7
#to allow everyone read access access
[/]
* = r
#Allow All Developers Complete Access
@Developers = rw
#give the doc people write access to the docs folder [/ project / trunk / doc]
@DOCS = RW
