# have been written to the final string if enough space had been available.
#
# Define FREAD_READS_DIRECTORIES if you are on a system which succeeds
-# when attempting to read from an fopen'ed directory.
+# when attempting to read from an fopen'ed directory (or even to fopen
+# it at all).
#
# Define NO_OPENSSL environment variable if you do not have OpenSSL.
# This also implies BLK_SHA1.
#
-# Define USE_LIBPCRE if you have and want to use libpcre. git-grep will be
-# able to use Perl-compatible regular expressions.
-#
-# Define LIBPCREDIR=/foo/bar if your libpcre header and library files are in
-# /foo/bar/include and /foo/bar/lib directories.
+# Define USE_LIBPCRE if you have and want to use libpcre. Various
+# commands such as log and grep offer runtime options to use
+# Perl-compatible regular expressions instead of standard or extended
+# POSIX regular expressions.
+#
+# Currently USE_LIBPCRE is a synonym for USE_LIBPCRE1, define
+# USE_LIBPCRE2 instead if you'd like to use version 2 of the PCRE
+# library. The USE_LIBPCRE flag will likely be changed to mean v2 by
+# default in future releases.
+#
+# When using USE_LIBPCRE1, define NO_LIBPCRE1_JIT if the PCRE v1
+# library is compiled without --enable-jit. We will auto-detect
+# whether the version of the PCRE v1 library in use has JIT support at
+# all, but we unfortunately can't auto-detect whether JIT support
+# hasn't been compiled in in an otherwise JIT-supporting version. If
+# you have link-time errors about a missing `pcre_jit_exec` define
+# this, or recompile PCRE v1 with --enable-jit.
+#
+# Define LIBPCREDIR=/foo/bar if your PCRE header and library files are
+# in /foo/bar/include and /foo/bar/lib directories. Which version of
+# PCRE this points to determined by the USE_LIBPCRE1 and USE_LIBPCRE2
+# variables.
#
# Define HAVE_ALLOCA_H if you have working alloca(3) defined in that header.
#
# Define PPC_SHA1 environment variable when running make to make use of
# a bundled SHA1 routine optimized for PowerPC.
#
+# Define DC_SHA1 to unconditionally enable the collision-detecting sha1
+# algorithm. This is slower, but may detect attempted collision attacks.
+# Takes priority over other *_SHA1 knobs.
+#
+# Define DC_SHA1_SUBMODULE in addition to DC_SHA1 to use the
+# sha1collisiondetection shipped as a submodule instead of the
+# non-submodule copy in sha1dc/. This is an experimental option used
+# by the git project to migrate to using sha1collisiondetection as a
+# submodule.
+#
+# Define OPENSSL_SHA1 environment variable when running make to link
+# with the SHA1 routine from openssl library.
+#
# Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed
# in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO
# wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined.
