NAME

       tred - transitive reduction filter for directed graphs

SYNOPSIS

       tred [ files ]

DESCRIPTION

       tred  computes  the  transitive reduction of directed graphs, and prints the resulting graphs to standard
       output.  This removes edges implied by transitivity.  Nodes and subgraphs  are  not  otherwise  affected.
       The ``meaning'' and validity of the reduced graphs is application dependent.  tred is particularly useful
       as a preprocessor to dot to reduce clutter in dense layouts.

       Undirected graphs are silently ignored.

OPERANDS

       The following operand is supported:

       files   Names of files containing 1 or more graphs in dot format.  If no files operand is specified,  the
               standard input will be used.

BUGS

       Using bitmaps internally would substantially decrease running time.

DIAGNOSTICS

       If  a  graph  has  cycles,  its  transitive reduction is not uniquely defined.  In this case tred emits a
       warning.
