xsl script to generate graphical representation of build.xml

[Stefan Kost]

hi,

attached you find a xsl script, which generates a .dot out of a
build.xml file. The dot file can be rendered using the dot command (from
the graphviz package, see http://www.graphviz.org/) to lots of formats
like ps or png.
Minimal instructions are in the xsl file.

Stefan
