-# Currently USE_LIBPCRE is a synonym for USE_LIBPCRE1, define

-# default in future releases.
+# USE_LIBPCRE is a synonym for USE_LIBPCRE2, define USE_LIBPCRE1
+# instead if you'd like to use the legacy version 1 of the PCRE
+# library. Support for version 1 will likely be removed in some future
+# release of Git, as upstream has all but abandoned it.
#
# When using USE_LIBPCRE1, define NO_LIBPCRE1_JIT if the PCRE v1
# library is compiled without --enable-jit. We will auto-detect
#
# Define NO_PERL if you do not want Perl scripts or libraries at all.
#
+# Define NO_PERL_CPAN_FALLBACKS if you do not want to install bundled
+# copies of CPAN modules that serve as a fallback in case the modules
+# are not available on the system. This option is intended for
+# distributions that want to use their packaged versions of Perl
+# modules, instead of the fallbacks shipped with Git.
+#
# Define PYTHON_PATH to the path of your Python binary (often /usr/bin/python
# but /usr/bin/python2.7 on some platforms).
#
# when hardlinking a file to another name and unlinking the original file right
# away (some NTFS drivers seem to zero the contents in that scenario).
#
+# Define INSTALL_SYMLINKS if you prefer to have everything that can be
+# symlinked between bin/ and libexec/ to use relative symlinks between
+# the two. This option overrides NO_CROSS_DIRECTORY_HARDLINKS and
+# NO_INSTALL_HARDLINKS which will also use symlinking by indirection
+# within the same directory in some cases, INSTALL_SYMLINKS will
+# always symlink to the final target directly.
+#
# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
# programs as a tar, where bin/ and libexec/ might be on different file systems.
#
#
# When cross-compiling, define HOST_CPU as the canonical name of the CPU on
# which the built Git will run (for instance "x86_64").
+#
+# Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
+# support files relative to the location of the runtime binary, rather than
+# hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
+# can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
+# Perl scripts to use a modified entry point header allowing them to resolve
+# support files at runtime.
+#
+# When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
+# supports the KERN_PROC BSD sysctl function.
+#
+# When using RUNTIME_PREFIX, define PROCFS_EXECUTABLE_PATH if your platform
+# mounts a "procfs" filesystem capable of resolving the path of the current
+# executable. If defined, this must be the canonical path for the "procfs"
+# current executable path.
+#
+# When using RUNTIME_PREFIX, define HAVE_NS_GET_EXECUTABLE_PATH if your platform
+# supports calling _NSGetExecutablePath to retrieve the path of the running
+# executable.
+#
+# When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
+# the global variable _wpgmptr containing the absolute path of the current
+# executable (this is the case on Windows).
