| at one time the two parsers handled differently languages,
| the 'old' boot language and the 'new' boot language. the
| boot parser was written in the old boot language and the
| rest of the system was coded in the new boot language.
| the goal was to unify the two language.

OK; as I'm trying to find my way through the system, is there a place
where I could find differences of the two languaes?

I'll try the second one.  However, for the moment, one of them seems
to put the result on the translation in the "int/" directory when I
really want it somewhere else.  It is not obvious from looking at the
code, how the the results end up in the "int/" directory.

| one of the parsers used to live in the boottran package
| and the other lived in the boot package. there is a subtle
| issue of which macros are loaded into each image which
| affects the ultimate expansion of the code.
