+# January 2007.

+# The code does not present direct interest to OpenSSL, because of low
+# performance. Its purpose is to establish _size_ benchmark. Pretty
+# useless one I must say, because 30% or 88 bytes larger ARMv4 code
+# [avialable on demand] is almost _twice_ as fast. It should also be
+# noted that in-lining of .Lcommon and .Lrotate improves performance
+# by over 40%, while code increases by only 10% or 32 bytes. But once
+# again, the goal was to establish _size_ benchmark, not performance.
