NAME
       tsort - topological sort

SYNOPSIS
       /usr/ccs/bin/tsort [file]

DESCRIPTION
       The  tsort  command  produces  on the standard output a totally ordered
       list of items consistent	with a partial ordering	of items mentioned  in
       the input file.

       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.

OPERANDS
       The following operand is	supported:

       file	A  path	 name  of  a text file to order. If no file operand is
		given, the standard input is used.
