# The files in this directory implement the read_graphviz() functions
# declared in <boost/graph/graphviz.hpp>. There are both directed
# and undirected graph versions of these functions. To use both, you
# will need to compile the code generated from graphviz_parser.y twice,
# once with -DGRAPHVIZ_DIRECTED=0 and once with -DGRAPHVIZ_DIRECTED=1.

# This Makefile will most likely *not* work on your system.
# We have not yet had time to create a portable Makefile.
# This is the Makefile we currently use.
