                     13: creates two
                     14: \*(II command files in the directory:
                     15: .bd Copy.out,
                     16: which contains Quel instuctions which will copy all relations owned by the user
                     17: into files in the named directory,
                     18: and
                     19: .bd copy.in,
                     20: which contains instructions to copy the files into relations,
                     21: create indexes and do modifies.
                     22: The files will have the same names as the relations with
                     23: the users \*(II id tacked on the end.
                     24: (The directory MUST NOT be the same as the data base directory
                     25: as the files have the same names as the relation files.)
                     26: The
                     27: .bd \-u
                     28: flag may be used to run
                     29: .it copydb
                     30: with a different user id.
                     31: (The fact that
                     32: .it copydb
                     33: creates the copy files does not imply that the user
                     34: can necessarily access the specified relation).
                     35: If relation names are specified only those relations will be
                     36: included in the
                     37: copy files.
                     38: .s3

                     40: is written in Equel and will access the database in the usual manner.
                     41: It does not have to run as
                     42: the \*(II user.

                     58: been specified on one relation.
                     59: The constant can be increased and the program recompiled.

                     65: cannot tell if the relation was modified with a fillfactor or
