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.

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.

12# Define CURLDIR=/foo/bar if your curl header and library files are in
13# /foo/bar/include and /foo/bar/lib directories.

20# Define ARM_SHA1 environment variable when running make to make use of

36# Define COLLISION_CHECK below if you believe that SHA1's
37# 1461501637330902918203684832716283019655932542976 hashes do not give you

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