! There are some differences between windows and unix relating to

! the two ooperating systems supported are included below 
! NOTE: Uses mkdir -p in unix which can build the whole path as opposed to mkdir which can only build the bottom level directory
! mkdir -p works in ubuntu 14.04 - not sure that this is a portable solution though...
