- I would like to create the fortran datatype for PetscBag (Barry: yes, I have a fortran fetish), but I am not completely sure where to start. In particular, how are the .h / .h90 in include/finclude/f90-auto created?

bfort should be creating these during fortranstub generation [either during configure step - or with 'make allfortranstubs']. If the c-code has a formatted comment that tells bfort to auto-generate fortran stub - it might also generate the 'interface' function and stash it in include/finclude/f90-auto.

That's where I get confused. Take src/sys/bag/bag.c : PetscBagCreate fortran binding is created automatically in ftn-auto, yet there is no include/finclude/ftn-auto/petscbag.h90 What am I missing?

Its added to petscsys.h90 - perhaps because there is no separate 'petscbag' section [in manpages or other places]. This info is obtained and processed from 'MANSEC' field in the corresponding makefile Satish
