include機能とC言語で直接記述できる機能を追加してます
digraph graphname { graph [rankdir = TB]; subgraph cluster0 { label="Compile"; b0 [label="car_m4(sed (include))" shape="rectangle"] b [label="car_m4(sed (here doc))" shape="rectangle"] c0 [label="m4 macro set" shape="box3d"] cc [label="tmpinc.m4"] c [label="tmp.m4"] d [label="car_m4(m4)" shape="rectangle"] e [label="mtASM src"] b -> c -> d; c0 -> d -> e; b0 -> cc ->b; {rank = same;c0;d;} } subgraph cluster1 { label="Assemble"; e0 [label="awk src1" shape="box3d"] f [label="car_mt(awk)" shape="rectangle"] f0 [label="C src"] ff [label="tmp C src"] f1 [label="template C src" shape="box3d"] g [label="car_mt(gcc)" shape="rectangle"] f1 -> g; ff ->g; e0 -> f; f -> f0 -> g; {rank = same; e0;f;} } a [label="Esgrsdnl src" shape="note"]; a0 [label="Esgrsdnl include src" shape="note"]; a1 [label="mtASM include src" shape="note"]; h [label="exe file" shape="Msquare"] i [label="bet file"] b -> ff; f ->i; a -> b0; a0 -> b0; a1 -> d; e -> f; g -> h; {rank = same; i;h;} }
こんな流れ
