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.
5 #
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.
8 #
9 # Define NO_CURL if you do not have curl installed. git-http-pull is not
10 # built, and you cannot use http:// and https:// transports.
11 #
12 # Define PPC_SHA1 environment variable when running make to make use of
13 # a bundled SHA1 routine optimized for PowerPC.

16 # Define COLLISION_CHECK below if you believe that SHA1's
17 # 1461501637330902918203684832716283019655932542976 hashes do not give you
18 # sufficient guarantee that no collisions between objects will ever happen.

22 # Define USE_NSEC below if you want git to care about sub-second file mtimes
23 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
24 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
25 # randomly break unless your underlying filesystem supports those sub-second
26 # times (my ext3 doesn't).
