/*********************************
*******Interactions code by HONKERTRON feat TestUnit********
**Contains a lot ammount of ERP and MEHANOYEBLYA**
**CREDIT TO ATMTA STATION FOR MOST OF THIS CODE, I ONLY MADE IT WORK IN /vg/ - Matt
** Rewritten 30/08/16 by Zuhayr, sry if I removed anything important.
**I removed ERP and replaced it with handholding. Nothing of worth was lost. - Vic
**Fuck you, Vic. ERP is back. - TT
**>using var/ on everything, also TRUE
