       rrccssddiiffff runs ddiiffff(1) to compare two revisions of each  RCS
       file given.

       Pathnames  matching  an  RCS  suffix denote RCS files; all
       others  denote  working  files.   Names  are   paired   as
       explained in ccii(1).

       The option --qq suppresses diagnostic output.  Zero, one, or
       two revisions  may  be  specified  with  --rr.   The  option
       --kk_s_u_b_s_t affects keyword substitution when extracting revi-
       sions, as described in ccoo(1); for example, --kkkk --rr11..11 --rr11..22
       ignores differences in keyword values when comparing revi-
       sions 11..11 and 11..22.  To avoid  excess  output  from  locker
       name  substitution,  --kkkkvvll  is  assumed if (1) at most one
       revision option is given, (2) no --kk option is  given,  (3)
       --kkkkvv  is  the  default  keyword  substitution, and (4) the
       working file's mode would be produced by ccoo --ll.  See ccoo(1)
       for  details  about  --VV and --xx.  Otherwise, all options of
       ddiiffff(1) that apply to regular files are accepted, with the
       same meaning as for ddiiffff.

       If  both  _r_e_v_1  and _r_e_v_2 are omitted, rrccssddiiffff compares the
       latest revision on the  default  branch  (by  default  the
       trunk)  with  the  contents  of  the corresponding working
       file.  This is useful for  determining  what  you  changed
       since the last checkin.

       If  _r_e_v_1  is  given, but _r_e_v_2 is omitted, rrccssddiiffff compares
       revision _r_e_v_1 of the RCS file with  the  contents  of  the
       corresponding working file.

       If  both  _r_e_v_1  and _r_e_v_2 are given, rrccssddiiffff compares revi-
       sions _r_e_v_1 and _r_e_v_2 of the RCS file.

       Both _r_e_v_1 and _r_e_v_2 may be given  numerically  or  symboli-
       cally.

       The command

               rrccssddiiffff  ff..cc

       compares  the latest revision on the default branch of the
       RCS file to the contents of the working file ff..cc.
