# If only vboxmanage, vboxheadless or such should be patched (and not the base script VBox) just use a list
# in the loop (eg. 'for i in virtualbox vboxmanage vboxheadless; do'). These links will be replaced by patched
# 'real' files. Of course it will not make sense if VBox is included in the list, then.
