TSORT(CP)                XENIX System V                 TSORT(CP)



     Name
          tsort - Sorts a file topologically.

     Syntax
          tsort [ file ]

     Description
          tsort produces on the standard output a totally ordered list
          of items consistent with a partial ordering of items
          mentioned in the input file.  If no file is specified, the
          standard input is understood.

          The input consists of pairs of items (nonempty strings)
          separated by blanks.  Pairs of different items indicate
          ordering.  Pairs of identical items indicate presence, but
          not ordering.

     Diagnostics
          Odd data:  There is an odd number of fields in the input
                     file.

     Notes
          The sort algorithm is quadratic, which can be slow if you
          have a large input list.
