+There are blowfish assembler generation scripts.
+bf-586.pl version is for the pentium and
+bf-686.pl is my original version, which is faster on the pentium pro.
+
+When using a bf-586.pl, the pentium pro/II is %8 slower than using
+bf-686.pl.  When using a bf-686.pl, the pentium is %16 slower
+than bf-586.pl
+
+So the default is bf-586.pl
