+# Define MOZILLA_SHA1 environment variable when running make to make use of
+# a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
+# on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
+# choice) has very fast version optimized for i586.
+#
+# Define NO_OPENSSL environment variable if you do not have OpenSSL. You will
+# miss out git-rev-list --merge-order. This also implies MOZILLA_SHA1.
