* THIS IS NOT COMPATIBLE with the old 0.2xxx series of the Graph
module. Your scripts are likely to break. I did try to fashion a
nice compatibility mode but there was no way to do that cleanly
and to cover all the old oddities. You can try the compatibility
mode but I suggest changing your code instead because the compat
mode is not going to be carried over to the next releases of the
module.
* The main reason for introducing the incompatibilities was that
the new Graph supports graphs of 'higher dimensions', and the
assumptions made by the old module (most importantly that edges
could only span two vertices) in effect made it impossible to
extend the interfaces.
* The next version of Graph (most likely 0.90) is going to aim
for speed. The backward compatibility for the 0.2xxx series
will be dropped (because that, too, slows down this release).
This is a perl module for graph operations as the code was for the 1st edition
of "Mastering Algorithms with Perl", by Jon Orwant, Jarkko Hietaniemi, and John
Macdonald, published in August 1999 by the O'Reilly and Associates.
