+/* As for what this does - it's a largely unoptimised implementation of an
+ * ENGINE that uses the GMP library to perform RSA private key operations. To

+ * on the subject (though ignore the build instructions which have since
+ * changed);
+ *
+ * http://www.mail-archive.com/openssl-dev@openssl.org/msg12227.html
+ *
+ * On my athlon system at least, it appears the builtin OpenSSL code is now
+ * slightly faster, which is to say that the RSA-related MPI performance
+ * between OpenSSL's BIGNUM and GMP's mpz implementations is probably pretty
+ * balanced for this chip, and so the performance degradation in this ENGINE by
+ * having to convert to/from GMP formats (and not being able to cache
+ * montgomery forms) is probably the difference. However, if some unconfirmed
+ * reports from users is anything to go by, the situation on some other
+ * chipsets might be a good deal more favourable to the GMP version (eg. PPC).
+ * Feedback welcome. */
