Okay, that's what I thought and told them initially, but they feel quite 
strongly about this so I told them I would check.  Job done. :-)

Looking at the contents of the repo again I'm not sure they actually 
rearranged tht at all.  I think they may just have been defining a 
structure for their environment files and role definitions.  I probably 
need to follow up with them when they have a little more concrete idea 
of what they want to do around this.
