The logical opposite of data and code separation.
TWiki currently mixes data and code in standard installations. To encourage people to try a system with data & code separation a migration path back to their current setup needs to be put in place. (People are less likely to try it otherwise) As a result the TWikiUnixInstaller needs to have this facility and I needed to call it something .
