NAME
       unflatten - adjust directed graphs to improve layout aspect ratio

SYNOPSIS
       unflatten [-f] [-llen] [-clen ] [ -o outfile ] [ files ]

DESCRIPTION
       unflatten  is  a preprocessor to dot that is used to improve the aspect
       ratio of graphs having many leaves or disconnected  nodes.   The  usual
       layout  for  such  a  graph  is generally very wide or tall.  unflatten
       inserts invisible edges or adjusts the minlen on edges to improve  lay-
       out compaction.

OPTIONS
       The following options are supported:

       -l len The  minimum length of leaf edges is staggered between 1 and len
	      (a small integer).

       -f     Enables the staggering of the -l option to  fanout  nodes  whose
	      indegree	and  outdegree	are both 1. This helps with structures
	      such as a -> {w x y z} -> b.  This option only works if  the  -l
	      flag is set.

       -c len Form disconnected nodes into chains of up to len nodes.

       -o outfile
	      causes  the  output  to  be  written  to	the specified file; by
	      default, output is written to stdout.

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.
