The site version of setup_paths may be used to split the Yohkoh database across multiple disks or machines. It is also used to define the areas where the software will search for reformatted files. It resolves top level environmentals with site specific path names. Local pathnames should include NFS names (per fstab) if database or reformatted files are shared among machines. The file: $ys/gen/setup/setup_paths may be used as a template if $ys/site/setup/setup_paths does not already exist. It includes some internal documentation and examples.
