# The default target of this Makefile is...
all:

# 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.
# This also implies MOZILLA_SHA1.
#
# Define NO_CURL if you do not have curl installed.  git-http-pull and
# git-http-push are not built, and you cannot use http:// and https://
# transports.
#
# Define CURLDIR=/foo/bar if your curl header and library files are in
# /foo/bar/include and /foo/bar/lib directories.
#
# Define NO_EXPAT if you do not have expat installed.  git-http-push is
# not built, and you cannot push using http:// and https:// transports.
#
# Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
#
# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
# d_type in struct dirent (latest Cygwin -- will be fixed soonish).
#
# Define NO_STRCASESTR if you don't have strcasestr.
#
# Define NO_SETENV if you don't have setenv in the C library.
#
# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
# Enable it on Windows.  By default, symrefs are still used.
#
# Define PPC_SHA1 environment variable when running make to make use of
# a bundled SHA1 routine optimized for PowerPC.
#
# Define ARM_SHA1 environment variable when running make to make use of
# a bundled SHA1 routine optimized for ARM.
#
# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
#
# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
#
# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
# Patrick Mauritz).
#
# Define NO_MMAP if you want to avoid mmap.
#
# Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
#
# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
#
# Define NO_SOCKADDR_STORAGE if your platform does not have struct
# sockaddr_storage.
#
# Define NO_ICONV if your libc does not properly support iconv.
#
# Define NO_ACCURATE_DIFF if your diff program at least sometimes misses
# a missing newline at the end of the file.
#
# Define NO_PYTHON if you want to loose all benefits of the recursive merge.
#
# Define COLLISION_CHECK below if you believe that SHA1's
# 1461501637330902918203684832716283019655932542976 hashes do not give you
# sufficient guarantee that no collisions between objects will ever happen.

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

# Define USE_STDEV below if you want git to care about the underlying device
# change being considered an inode change from the update-cache perspective.
