[OTR-users] OTR Perl Module

[Patrick Tierney]

Great, that worked!  For future information, my final .xs code looks like this:

#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
#include "INLINE.h"

#define context otr_context
#include <libotr/context.h>
#undef context

#include <libotr/proto.h>
#include <libotr/message.h>
#include <libotr/privkey.h>
