Module format 

Format files: dumping the engine state after an IniTeX run (\dump) and loading it at the start of a normal run.

The format is retex’s own binary layout, not LuaTeX’s. It is a sequence of sections (engine, then host-specific sections such as Lua bytecode), each a length-prefixed blob, behind a header that identifies the retex build. Integers are LEB128 varints (zigzag for signed values). Only non-default entries of the large tables are stored, so loading is fast.
