This is very very very old code !
We tried to eliminate such code in Dolphin 7 as much as possible ! But there are a lot of such things, almost everywhere .. it was written for years ..
Dolphin 7 is much better than Dolphin 6 .. most of the functionality was moved to modules and templates was completely separated. But some old things are still in the code.

In the future we will get rid of such code at all !
