NEW FEATURES
Added a collection of graph processing tools:
acyclic : a filter that takes a directed graph as input
and outputs a copy of the graph with sufficient edges
reversed to make the graph acyclic.
ccomps : decomposes graphs into their connected components,
printing the components to standard output.
colorize : is a filter that sets node colors from initial
seed values. Colors flow along edges from tail to head.
gc : a graph analogue to wc in that it prints to standard
output the number of nodes, edges, connected components or
clusters contained in the input files.
gpr : a graph stream editor inspired by awk. It copies
input graphs to its output, possibly transforming their
structure and attributes, creating new graphs, or
printing arbitrary information.
nop : reads a stream of graphs and prints each in
pretty-printed (canonical) format on stdout.
sccmap : decomposes digraphs into strongly connected components
and an auxiliary map of the relationship between components.
tred : computes the transitive reduction of directed graphs,
and prints the resulting graphs to standard output. This
removes edges implied by transitivity.
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 layout compaction.
FIXES

Change PNG default background color from transparent to white
because of the difficulty some viewers have with transparency.
