-Building and installing a packaged release of jemalloc can be as simple as
-typing the following while in the root directory of the source tree:
-
-    ./configure
-    make
-    make install
-
-If building from unpackaged developer sources, the simplest command sequence
-that might work is:
-
-    ./autogen.sh
-    make dist
-    make
-    make install
-
-Note that documentation is not built by the default target because doing so
-would create a dependency on xsltproc in packaged releases, hence the
-requirement to either run 'make dist' or avoid installing docs via the various
-install_* targets documented below.
-
-=== Advanced configuration =====================================================
-
-The 'configure' script supports numerous options that allow control of which
-functionality is enabled, where jemalloc is installed, etc.  Optionally, pass
-any of the following arguments (not a definitive list) to 'configure':
-
---help
-    Print a definitive list of options.
-
---prefix=<install-root-dir>
-    Set the base directory in which to install.  For example:
-
-        ./configure --prefix=/usr/local
-
-    will cause files to be installed into /usr/local/include, /usr/local/lib,
-    and /usr/local/man.
-
---with-version=<major>.<minor>.<bugfix>-<nrev>-g<gid>
-    Use the specified version string rather than trying to generate one (if in
-    a git repository) or use existing the VERSION file (if present).
-
---with-rpath=<colon-separated-rpath>
-    Embed one or more library paths, so that libjemalloc can find the libraries
-    it is linked to.  This works only on ELF-based systems.
-
---with-mangling=<map>
-    Mangle public symbols specified in <map> which is a comma-separated list of
-    name:mangled pairs.
-
-    For example, to use ld's --wrap option as an alternative method for
-    overriding libc's malloc implementation, specify something like:
-
-      --with-mangling=malloc:__wrap_malloc,free:__wrap_free[...]
-
-    Note that mangling happens prior to application of the prefix specified by
-    --with-jemalloc-prefix, and mangled symbols are then ignored when applying
-    the prefix.
-
---with-jemalloc-prefix=<prefix>
-    Prefix all public APIs with <prefix>.  For example, if <prefix> is
-    "prefix_", API changes like the following occur:
-
-      malloc()         --> prefix_malloc()
-      malloc_conf      --> prefix_malloc_conf
-      /etc/malloc.conf --> /etc/prefix_malloc.conf
-      MALLOC_CONF      --> PREFIX_MALLOC_CONF
-
-    This makes it possible to use jemalloc at the same time as the system
-    allocator, or even to use multiple copies of jemalloc simultaneously.
-
-    By default, the prefix is "", except on OS X, where it is "je_".  On OS X,
-    jemalloc overlays the default malloc zone, but makes no attempt to actually
-    replace the "malloc", "calloc", etc. symbols.
-
---without-export
-    Don't export public APIs.  This can be useful when building jemalloc as a
-    static library, or to avoid exporting public APIs when using the zone
-    allocator on OSX.
-
---with-private-namespace=<prefix>
-    Prefix all library-private APIs with <prefix>je_.  For shared libraries,
-    symbol visibility mechanisms prevent these symbols from being exported, but
-    for static libraries, naming collisions are a real possibility.  By
-    default, <prefix> is empty, which results in a symbol prefix of je_ .
-
---with-install-suffix=<suffix>
-    Append <suffix> to the base name of all installed files, such that multiple
-    versions of jemalloc can coexist in the same installation directory.  For
-    example, libjemalloc.so.0 becomes libjemalloc<suffix>.so.0.
-
---with-malloc-conf=<malloc_conf>
-    Embed <malloc_conf> as a run-time options string that is processed prior to
-    the malloc_conf global variable, the /etc/malloc.conf symlink, and the
-    MALLOC_CONF environment variable.  For example, to change the default chunk
-    size to 256 KiB:
-
-      --with-malloc-conf=lg_chunk:18
-
---disable-cc-silence
-    Disable code that silences non-useful compiler warnings.  This is mainly
-    useful during development when auditing the set of warnings that are being
-    silenced.
-
---enable-debug
-    Enable assertions and validation code.  This incurs a substantial
-    performance hit, but is very useful during application development.
-    Implies --enable-ivsalloc.
-
---enable-code-coverage
-    Enable code coverage support, for use during jemalloc test development.
-    Additional testing targets are available if this option is enabled:
-
-      coverage
-      coverage_unit
-      coverage_integration
-      coverage_stress
-
-    These targets do not clear code coverage results from previous runs, and
-    there are interactions between the various coverage targets, so it is
-    usually advisable to run 'make clean' between repeated code coverage runs.
-
---disable-stats
-    Disable statistics gathering functionality.  See the "opt.stats_print"
-    option documentation for usage details.
-
---enable-ivsalloc
-    Enable validation code, which verifies that pointers reside within
-    jemalloc-owned chunks before dereferencing them.  This incurs a minor
-    performance hit.
-
---enable-prof
-    Enable heap profiling and leak detection functionality.  See the "opt.prof"
-    option documentation for usage details.  When enabled, there are several
-    approaches to backtracing, and the configure script chooses the first one
-    in the following list that appears to function correctly:
-
-    + libunwind      (requires --enable-prof-libunwind)
-    + libgcc         (unless --disable-prof-libgcc)
-    + gcc intrinsics (unless --disable-prof-gcc)
-
---enable-prof-libunwind
-    Use the libunwind library (http://www.nongnu.org/libunwind/) for stack
-    backtracing.
-
---disable-prof-libgcc
-    Disable the use of libgcc's backtracing functionality.
-
---disable-prof-gcc
-    Disable the use of gcc intrinsics for backtracing.
-
---with-static-libunwind=<libunwind.a>
-    Statically link against the specified libunwind.a rather than dynamically
-    linking with -lunwind.
-
---disable-tcache
-    Disable thread-specific caches for small objects.  Objects are cached and
-    released in bulk, thus reducing the total number of mutex operations.  See
-    the "opt.tcache" option for usage details.
-
---disable-munmap
-    Disable virtual memory deallocation via munmap(2); instead keep track of
-    the virtual memory for later use.  munmap() is disabled by default (i.e.
-    --disable-munmap is implied) on Linux, which has a quirk in its virtual
-    memory allocation algorithm that causes semi-permanent VM map holes under
-    normal jemalloc operation.
-
---disable-fill
-    Disable support for junk/zero filling of memory, quarantine, and redzones.
-    See the "opt.junk", "opt.zero", "opt.quarantine", and "opt.redzone" option
-    documentation for usage details.
-
---disable-valgrind
-    Disable support for Valgrind.
-
---disable-zone-allocator
-    Disable zone allocator for Darwin.  This means jemalloc won't be hooked as
-    the default allocator on OSX/iOS.
-
---enable-utrace
-    Enable utrace(2)-based allocation tracing.  This feature is not broadly
-    portable (FreeBSD has it, but Linux and OS X do not).
-
---enable-xmalloc
-    Enable support for optional immediate termination due to out-of-memory
-    errors, as is commonly implemented by "xmalloc" wrapper function for malloc.
-    See the "opt.xmalloc" option documentation for usage details.
-
---enable-lazy-lock
-    Enable code that wraps pthread_create() to detect when an application
-    switches from single-threaded to multi-threaded mode, so that it can avoid
-    mutex locking/unlocking operations while in single-threaded mode.  In
-    practice, this feature usually has little impact on performance unless
-    thread-specific caching is disabled.
-
---disable-tls
-    Disable thread-local storage (TLS), which allows for fast access to
-    thread-local variables via the __thread keyword.  If TLS is available,
-    jemalloc uses it for several purposes.
-
---disable-cache-oblivious
-    Disable cache-oblivious large allocation alignment for large allocation
-    requests with no alignment constraints.  If this feature is disabled, all
-    large allocations are page-aligned as an implementation artifact, which can
-    severely harm CPU cache utilization.  However, the cache-oblivious layout
-    comes at the cost of one extra page per large allocation, which in the
-    most extreme case increases physical memory usage for the 16 KiB size class
-    to 20 KiB.
-
---with-xslroot=<path>
-    Specify where to find DocBook XSL stylesheets when building the
-    documentation.
-
---with-lg-page=<lg-page>
-    Specify the base 2 log of the system page size.  This option is only useful
-    when cross compiling, since the configure script automatically determines
-    the host's page size by default.
-
---with-lg-page-sizes=<lg-page-sizes>
-    Specify the comma-separated base 2 logs of the page sizes to support.  This
-    option may be useful when cross-compiling in combination with
-    --with-lg-page, but its primary use case is for integration with FreeBSD's
-    libc, wherein jemalloc is embedded.
-
---with-lg-size-class-group=<lg-size-class-group>
-    Specify the base 2 log of how many size classes to use for each doubling in
-    size.  By default jemalloc uses <lg-size-class-group>=2, which results in
-    e.g. the following size classes:
-
-      [...], 64,
-      80, 96, 112, 128,
-      160, [...]
-
-    <lg-size-class-group>=3 results in e.g. the following size classes:
-
-      [...], 64,
-      72, 80, 88, 96, 104, 112, 120, 128,
-      144, [...]
-
-    The minimal <lg-size-class-group>=0 causes jemalloc to only provide size
-    classes that are powers of 2:
-
-      [...],
-      64,
-      128,
-      256,
-      [...]
-
-    An implementation detail currently limits the total number of small size
-    classes to 255, and a compilation error will result if the
-    <lg-size-class-group> you specify cannot be supported.  The limit is
-    roughly <lg-size-class-group>=4, depending on page size.
-
---with-lg-quantum=<lg-quantum>
-    Specify the base 2 log of the minimum allocation alignment.  jemalloc needs
-    to know the minimum alignment that meets the following C standard
-    requirement (quoted from the April 12, 2011 draft of the C11 standard):
-
-      The pointer returned if the allocation succeeds is suitably aligned so
-      that it may be assigned to a pointer to any type of object with a
-      fundamental alignment requirement and then used to access such an object
-      or an array of such objects in the space allocated [...]
-
-    This setting is architecture-specific, and although jemalloc includes known
-    safe values for the most commonly used modern architectures, there is a
-    wrinkle related to GNU libc (glibc) that may impact your choice of
-    <lg-quantum>.  On most modern architectures, this mandates 16-byte alignment
-    (<lg-quantum>=4), but the glibc developers chose not to meet this
-    requirement for performance reasons.  An old discussion can be found at
-    https://sourceware.org/bugzilla/show_bug.cgi?id=206 .  Unlike glibc,
-    jemalloc does follow the C standard by default (caveat: jemalloc
-    technically cheats if --with-lg-tiny-min is smaller than
-    --with-lg-quantum), but the fact that Linux systems already work around
-    this allocator noncompliance means that it is generally safe in practice to
-    let jemalloc's minimum alignment follow glibc's lead.  If you specify
-    --with-lg-quantum=3 during configuration, jemalloc will provide additional
-    size classes that are not 16-byte-aligned (24, 40, and 56, assuming
-    --with-lg-size-class-group=2).
-
---with-lg-tiny-min=<lg-tiny-min>
-    Specify the base 2 log of the minimum tiny size class to support.  Tiny
-    size classes are powers of 2 less than the quantum, and are only
-    incorporated if <lg-tiny-min> is less than <lg-quantum> (see
-    --with-lg-quantum).  Tiny size classes technically violate the C standard
-    requirement for minimum alignment, and crashes could conceivably result if
-    the compiler were to generate instructions that made alignment assumptions,
-    both because illegal instruction traps could result, and because accesses
-    could straddle page boundaries and cause segmentation faults due to
-    accessing unmapped addresses.
-
-    The default of <lg-tiny-min>=3 works well in practice even on architectures
-    that technically require 16-byte alignment, probably for the same reason
-    --with-lg-quantum=3 works.  Smaller tiny size classes can, and will, cause
-    crashes (see https://bugzilla.mozilla.org/show_bug.cgi?id=691003 for an
-    example).
-
-    This option is rarely useful, and is mainly provided as documentation of a
-    subtle implementation detail.  If you do use this option, specify a
-    value in [3, ..., <lg-quantum>].
-
-The following environment variables (not a definitive list) impact configure's
-behavior:
-
-CFLAGS="?"
-    Pass these flags to the compiler.  You probably shouldn't define this unless
-    you know what you are doing.  (Use EXTRA_CFLAGS instead.)
-
-EXTRA_CFLAGS="?"
-    Append these flags to CFLAGS.  This makes it possible to add flags such as
-    -Werror, while allowing the configure script to determine what other flags
-    are appropriate for the specified configuration.
-
-    The configure script specifically checks whether an optimization flag (-O*)
-    is specified in EXTRA_CFLAGS, and refrains from specifying an optimization
-    level if it finds that one has already been specified.
-
-CPPFLAGS="?"
-    Pass these flags to the C preprocessor.  Note that CFLAGS is not passed to
-    'cpp' when 'configure' is looking for include files, so you must use
-    CPPFLAGS instead if you need to help 'configure' find header files.
-
-LD_LIBRARY_PATH="?"
-    'ld' uses this colon-separated list to find libraries.
-
-LDFLAGS="?"
-    Pass these flags when linking.
-
-PATH="?"
-    'configure' uses this to find programs.
-
-=== Advanced compilation =======================================================
-
-To build only parts of jemalloc, use the following targets:
-
-    build_lib_shared
-    build_lib_static
-    build_lib
-    build_doc_html
-    build_doc_man
-    build_doc
-
-To install only parts of jemalloc, use the following targets:
-
-    install_bin
-    install_include
-    install_lib_shared
-    install_lib_static
-    install_lib
-    install_doc_html
-    install_doc_man
-    install_doc
-
-To clean up build results to varying degrees, use the following make targets:
-
-    clean
-    distclean
-    relclean
-
-=== Advanced installation ======================================================
-
-Optionally, define make variables when invoking make, including (not
-exclusively):
-
-INCLUDEDIR="?"
-    Use this as the installation prefix for header files.
-
-LIBDIR="?"
-    Use this as the installation prefix for libraries.
-
-MANDIR="?"
-    Use this as the installation prefix for man pages.
-
-DESTDIR="?"
-    Prepend DESTDIR to INCLUDEDIR, LIBDIR, DATADIR, and MANDIR.  This is useful
-    when installing to a different path than was specified via --prefix.
-
-CC="?"
-    Use this to invoke the C compiler.
-
-CFLAGS="?"
-    Pass these flags to the compiler.
-
-CPPFLAGS="?"
-    Pass these flags to the C preprocessor.
-
-LDFLAGS="?"
-    Pass these flags when linking.
-
-PATH="?"
-    Use this to search for programs used during configuration and building.
-
-=== Development ================================================================
-
-If you intend to make non-trivial changes to jemalloc, use the 'autogen.sh'
-script rather than 'configure'.  This re-generates 'configure', enables
-configuration dependency rules, and enables re-generation of automatically
-generated source files.
-
-The build system supports using an object directory separate from the source
-tree.  For example, you can create an 'obj' directory, and from within that
-directory, issue configuration and build commands:
-
-    autoconf
-    mkdir obj
-    cd obj
-    ../configure --enable-autogen
-    make
-
-=== Documentation ==============================================================
-
-The manual page is generated in both html and roff formats.  Any web browser
-can be used to view the html manual.  The roff manual page can be formatted
-prior to installation via the following command:
-
-    nroff -man -t doc/jemalloc.3
