 The OpenSSL headers are huge (>35k LOC) and make quite liberal use of the C
 preprocessor, and thus a fully automatic translation is as desirable as
 it is infeasible. This repository contains the result of a semi-automatic
 approach, and while all header files have been ported (and successfully
 compile), some preprocessor artifacts still need to be ported (currently
