But Paulo didn't write it _either_
If you go back in time to 2003:
https://github.com/LinuxCNC/linuxcnc/blob/07bc1e161f834d8b192fe279819261294e5fe150/src/rtapi/procfs_macros.h
and compare that to a 1999 version of the RTAI file, the only line in
common is "#include "
At some point _both_ files included a chunk of work from Erwin Rol:
// proc print macros - Contributed by: Erwin Rol (er...@muffin.org)
_Most_ of both files was written by Erwin Rol. But both files existed
previously, and separately, as far as I can tell looking back in both
archives.
