TRED(1) 						      General Commands Manual							   TRED(1)

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 depen-
       dent.  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.
