[OpenSER-Users] test operator

[Klaus Darilion]

Hi!

from the core cookbook of 1.2:

> If you want to evaluate arithmetic operations and test the value in 
> conditions, use the test operator ' [ ... ] ' . This is required to 
> convert the result to internal convention for drop, true and false.

>    xlog("bit 3 is set in var a");

Is there somewhere a detailed description of the test operator? Can it 
only be used to test for 0/1 or can I also do comparison like e.g.
if ([ $rd == "mydomain.at" ]) ?
