tombstone.sty is a LaTeX package for drawing tombstone diagrams.
Simply copy the tombstone.sty file to the root directory of your projects and include it in your document using
\usepackage{tombstone}
The diagram in this readme was generated using the following code
\begin{tikzpicture}
\begin{tombstonediagram}
\compiler{cmp}{Java}{JVM}{JVM}{}
\program[anchor=prg-2-2.north east]{prg}{Tetris}{Java}{at (cmp-1-1.north west)}
\interpreter{int}{JVM}{x86}{at (cmp-2-2.south west)}
\program{prgo}{Tetris}{JVM}{at (cmp-1-3.north east)}
\machine{mac}{x86}{at (int-2-1.south west)}
\end{tombstonediagram}
\end{tikzpicture}
The package is documented in the file tombstonedoc.tex. A compiled PDF version of the documentation is also included in the repository.
