[O] verbatim and apostrophes

[Alan Schmitt]

Hello,

I want to generate some verbatim/code inline text that contains an
apostrophe (I want to talk about the ocaml type 'a ref). Unfortunately I
don't know how to do this. I tried:

- ~'a ref~
- ='a ref=
- ~\' a ref~
- =\'a ref=

The first two display everything (including the '~' or '=') but not as
code, the last two work but display the backquote.

I feel like I'm missing something obvious. Could someone enlighten me?

Thanks,

Alan
