--- Comment #1 from Michael Dexter <editor@callfortesting.org> ---
Some background kindly from the wilds that may help with a concise descript=
ion:

"CTF is designed to represent C types in a more compact format (and simply)
than DWARF. It's used extensively in illumos with dtrace, as well as for sy=
stem
debugging. ctfmerge specifically will uniqify the data from all the
constitutate .o files (think how many files will have a definition of pid_t,
etc)"

ctf.h#L38-L56
