tsort - topological sort
SYNOPSIS

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.
