SVN access rule

[groups]
sdk-developer = man1
sdk2-developer = man2
everyone = man1, man2, man3, man4

[MyRepo:/private]
@everyone = r

[MyRepo:/private/sdk]
@sdk-developer = rw
@sdk2-developer = r
@everyone =

Note: man3 and man4 can't access /private/sdk due to the limitation of last rule "@everyone =".
If the last rule is missed, for people not included in the list will use the rule which inherited from parent directory, then they will have "r" permission and be able to access /private/sdk.
