[QBS] Functions in QBS scripts and accessing properties from them.

As I know, you can create a custom *.config file in which to specify paths
to your toolchain, and then pass to qbs this your config file. Then qbs
will take your profile as default profile..
If I am not mistaken...

PS: For me too very interestingly any HOWTO for setup of custom
toolchain/profile for qbs. So, I also join to this question. :)
