+/// Demonstrate a boost::filesystem oddity.
+///
+/// A print directory is specified in 'configurable_settings.xml', and
+/// managed by 'preferences_model.cpp'. Using an msw build of lmi to
+/// change its value endues it with a 'root-name'. Subsequently using
+/// a posix build of lmi does not remove the 'root-name'; instead, it
+/// does something bizarre, viz.:
+///   fs::system_complete(/opt/lmi/data) returns:
+///   /opt/lmi/data
+///   fs::system_complete(Z:/opt/lmi/data) returns:
+///   /opt/lmi/gcc_x86_64-pc-linux-gnu/build/ship/Z:/opt/lmi/data
