Comment (by rhaas):

 Not having looked into this any further, I'd like to re-iterate my
 comments on this in different ET calls: since this breaks backwards
 compatibility to the old LORENE code (it cannot read files written by the
 old code. Does the LORENE C++ API also change?) I would prefer if the
 thorn was called LORENE2 and also implemented LORENE2. Ideally it should
 be able to compile both LORENE and LORENE2 into the same executable. If
 not possible (since we don't control the names of LORENE's externally
 visible symbols) then one could at least try that one at least receives an
 error before the final link stage (or not at all since the linker normally
 just ignore duplicate symbols [without --whole-archive]).
