  of C/C++ and Fortran data structures, and a tool for reading Lua tables into those structures. It is built around the observation that the textual representation of Lua table elements can frequently be mapped directly into a C/C++ struct, or a Fortran derived type. Suppose a Lua table constructor is given as follows: t1 = {t2 = {x=42,}}
