Subject: ocamlyacc and error recovery

[ ENGLISH AT BOTTOM OF MESSAGE ]

J'ai un petit probleme avec ocamlyacc lorsque je veux pouvoir gerer les
erreurs. Je n'arrive pas a utiliser le pseudo-token "error". La
documentation de caml est tres breve a ce sujet et renvoie aux documents
sur yacc... qui traitent de yacc pour le langage C et ne disent evidemment
pas comment rattraper les erreurs sous ocamlyacc!

J'ai toujours une exception Parse_error qui n'est jamais rattrapee.
Quelqu'un sait-il comment utiliser le token "error"?

[=== ENGLISH ===]

I have a small problem with ocamlyacc when I want to handle errors. I
can't get the "error" token to work. The caml documentation is very terse
on the subject and points to standard texts about yacc... which deal with
C-language yacc, not the particular points of ocamlyacc.

I always have an uncaught Parser_error exception. Does anyone know how to
handle the "error" token?
