[Devel] new features: script variables and pseudo-variables in script

[Daniel-Constantin Mierla]

Hello,

it is not possible to return a string from a function exported by a 
module now. The usual way is to use avps for that.

The exec module on devel is already extended with such feature you are 
looking for -- see exec_avp():
http://www.openser.org/docs/modules/1.2.x/exec.html#AEN134

Cheers,
Daniel
