           _W_h_a_t searches the given files for all occurrences of the
           pattern that _g_e_t(1) substitutes for %Z% (this is @@@@((((####)))) at
           this printing) and prints out what follows until the first
           """", >>>>, new-line, \\\\, or null character.  For example, if the C
           program in file ffff....cccc contains

                char ident[] = "@(#)identification information";

           and ffff....cccc is compiled to yield ffff....oooo and aaaa....oooouuuutttt, then the command

                what f....c f....o a....out

           will print

                f....c:
                        identification information

                f....o:
                        identification information

                a....out:
                        identification information

           _W_h_a_t is intended to be used in conjunction with the  command
           _g_e_t(1), which automatically inserts identifying information,
           but it can also be used where the information is inserted
           manually.

           Use _h_e_l_p(1) for explanations.

      BBBBUUUUGGGGSSSS
           It's possible that an unintended occurrence of the pattern
           @@@@((((####)))) could be found just by chance, but this causes no harm
           in nearly all cases.
