    NAME
         tsort - topological sort

    SYNOPSIS
         tsort [ file ]

    DESCRIPTION
         Tsort produces on the standard output a totally ordered list
         of items consistent with a partial ordering of items men-
         tioned 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 ord-
         ering.  Pairs of identical items indicate presence, but not
         ordering.

    SEE ALSO
         lorder(1)

    DIAGNOSTICS
         Odd data: there is an odd number of fields in the input
         file.

    BUGS
         Uses a quadratic algorithm; not worth fixing for the typical
         use of ordering a library archive file.
