+ * This is my modest contributon to the OpenSSL project (see
+ * http://www.openssl.org/ for more information about it) and is
+ * a drop-in MIPS III/IV ISA replacement for crypto/bn/bn_asm.c
+ * module. For updates see http://fy.chalmers.se/~appro/hpe/.
+ *
+ * The module is designed to work with "new" IRIX ABI(5), namely
+ * N32 and N64. But it was tested only with MIPSpro 7.2.x assembler,
+ * i.e. depends on preprocessor options set up by MIPSspro 7.2.x
+ * driver. Another neat gadget offered by MIPSpro 7.2.x assembler is
+ * an peep-hole(?) optimization pass. This gave me the opportunity
+ * to make the code looking more regular as all those architecture
+ * dependent(!) instruction rescheduling details were left to the
+ * assembler. Cool, huh? Do note that I have no idea if GNU assembler
+ * does anything similar nor how GNU C will do with this module.
+ * Feedback on the matter is therefore very much appreciated:-)
+ *
+ * Performance improvement is astonishing! 'apps/openssl speed rsa dsa'
+ * exhibits 3-3.5-3.7 times improvement!
