This option may be used to request that the symbolic links, or hard links, or file copies, in
the work area be updated to reflect the current state of the baseline. This is controlled by
the development_directory_style field of the project configuration file. Only files which are
not involved in the change are updated. See also the “symbolic_links_preference” field of
aeuconf(5). This option is the default, if meaningful for your configuration. The name is an
historical accident, hard links and file copies are included.
