qmake CONFIG function documentation lacks clarity

The documentation for the qmake CONFIG function has the following sentence, which is not really clear:

This is the same as regular old style (tmake) scopes, but has the added advantage a second parameter can be passed to test for the active config.

http://doc-snapshot.qt-project.org/4.8/qmake-function-reference.html#config-config

Deleting the sentence that mentions "old style (tmake) scopes" should be considered. It's a distraction, especially for those who have no idea what tmake is.

As as suggestion, the next sentence should read:

As the order of values is important in CONFIG variables (i.e. the last one set will be considered the active config for mutually exclusive values) a second parameter can be used to specify the set of exclusive values to consider.
