The reference doc is always "oasis manual" (i.e. call your oasis exec
with argument manual).

I agree that the website is not up to date and that I should solve this.

FYI, XMETAExtraLines is in the "oasis manual" doc.

In any case, these stack traces are completely useless to the user you should remove them, it's only noise. A tool should only return a stack trace if it has an internal error. Find an example at the end of this email.

I thought the trace was useful... Seems like you don't like it.

Do you have set OCAMLRUNPARAMS=b in your environment ? Turning it off
should probably turn of the stack trace as well.

Concerning the line number, this is clearly a bug and I was too lazy
to solve it. Feel free to fill a bug so that I won't forget about this
issue.
