We give an account of the C-SHORe tool, which contributed to the ongoing quest for a truly scalable model-checker for HORS by offering a different, automata theoretic perspective. C-SHORe implements the first practical model-checking algorithm that acts on a generalisation of pushdown automata equi-expressive with HORS called collapsible pushdown systems (CPDS).
