3. Machine-Specific Tokens
tokens/ is for os-machine specific definitions of implementation-defined things? like INT_MAX, sizeof(int), etc (write these in TDFese) these are defined in tpl, which is just a more convenient-to-write TDF. They could just as well be written in TDF directly. you *could* also use tokens/ to write machine-specific optimised routines
i guess you need to add stuff to src/lib/machines/$os/$arch/tokens, but i don't understand those yet. they're machine-specific implementations of abstract TDF tokens, written in TPL?
