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 mentioned in the input
       file.  If no file is specified, the standard input is used.

       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: the input file has an odd number of fields.

SEE ALSO
       lorder(1).
