  13:  * If a prefix is "abc", for example,
  14:  * then any file Spool/abc... is mapped to Spool/abc/abc... .
  15:  * The first prefix found is used, so D.foo should preceed D. in table.
  16:  *
  17:  * Each prefix must be a subdirectory of Spool, owned by uucp!
  18:  * Remember: use cron to uuclean these directories daily,
  19:  * and check them manually every now and then.  Beware complacency!
