Hello,

The patchwork tool doesn't seem to work any more:

$ patchwork -Nshape=polygon -Tdot -o graph-patchwork.dot graph.dot
There is no layout engine support for "patchwork"
 Use one of: dot

dot is indeed the layout I passed as parameter.

I also tried the unstable version with the same result, I had to revert
to the version from stable.

 Can you please retry your test? I think it should work. If not,
please send me your dot file.

Thanks,

I have tried version 14.1.1-2 with the same result.

strict digraph deps {
"foo" -> "bar"
}

 Can you please try 14.1.2-1 with the addition of
libgvplugin-neato-layout installed?
Do you know how many users of patchwork might be out there? I think
this binary should be moved to the graphviz-tools package.

The additional installation of libgvplugin-neato-layout did the trick
indeed!

I have no idea :)
