What's the meaning of formatted comments like the following (from cg.c)? I would guess this is used by sowing, but I can't find a good source of documentation.
This info might be added to the developer's guide (which also has an outdated link to info on sowing) - I could make a patch or branch based on the answer to this question. #include <../src/ksp/ksp/impls/cg/cgimpl.h> /*I "petscksp.h" I*/
