1# Define MOZILLA_SHA1 environment variable when running make to make use of
2# a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
3# on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
4# choice) has very fast version optimized for i586.

6# Define NO_OPENSSL environment variable if you do not have OpenSSL. You will
7# miss out git-rev-list --merge-order. This also implies MOZILLA_SHA1.

10# built, and you cannot use http:// and https:// transports.
