Object scope

The parser operates within the context of object scopes. An object scope is the set of all statements that follow an object name. The object scope terminates when another object name appears, or when the end of file is reached. Object names are specified by surrounding a string label with hard brackets. In this sample source code file, there are two base objects, [A] and [B], each with three statements in their scope.

[A] type = file path = /etc/sysconfig/network permissions = 640
[B] type = file path = /etc/sysconfig/rsyslog permissions = 640
