#Wrapper for unison (filesystem syncronizer)
#Edits unison's config file depending on which host you are
#You can use it to synchronize your data between two machiness (Laptop - PC)
#On both machines you only need to type "unison-wrapper.sh"
# 
# This script is unsupported. My girfriend has my old PC and I have a new
# laptop.
