Harald Welte 5bad900708 new gen_ladder implementation, based on the GD perl module 
This version generates PNG graphics based on the perl GD bindings and no
longer uses dot craphics.  This solves the long-standing problems that
existed with dot and 'bent arrows'

TODO:
	* re-add support for dashed arrows
	* re-add support for bi-directional arrows

gen_ladder - tool to generate protocol ladder diagrams
(C) 2010 by Harald Welte <laforge@gnumonks.org>

This tool can be used to generate typical ladder diagrams as they are often
used in the description of networking protocols.

The input file is a ".lad" file, from which gen_ladder.pl generates a graphviz
file called ".dot", which in turn can be processed by the "dot" program to
generate a .ps (postscript) or .svg output file.

As an example, I have included a "test.lad" file, which you can process by
calling
	make test.ps
or
	make test.svg

The manual intermediate steps can be seen from the Makefile.
