-Naming conventions of the libraries
-===================================
-
-Sometimes you need to have different versions of a library compiled with
-different options. Suppose you want to compile a library with profiling
-information enabled so that you can profile your code. But you don't want to
-overwrite your existing installed library so that only some of the applications
-will work with the profile library, the rest will still use the normal library.
-
-The makefile package supports such a schema by having different names for
-different types of the same library. This works by appending an underscore
-after the name of the library followed by a letter which indicates the type of
-the library:
-
-'s' for a static library
-'p' for a profile library
-'d' for a debug library
-
-So for example if you have the library 'example' compiled with debug
-information as a shared library it would be named libexample_d.so. If the same
-library is compiled as a static library its name would be named
-libexample_sd.a. The reason why the 's' letter for the static library appears
-in name of the library is for systems where the extensions of libraries don't
-matter.
-
-It is possible to compile a library with whatever combination of flags you
-want. The letters are appended in the order specified above, so if you compile
-the library as a static library, with profile and debug information enabled,
-the library name will have the _spd suffix appended.
-
-How a library is chosen
-=======================
-
-What happens if you compile an application with profile enabled and you don't
-have a library compiled with profile info into it, but you do have a normal
-library installed? It would be great if the normal library is chosen instead.
-This is a problem because the library that should be chosen has a different
-name than the profile library.
-
-We do support this schema by requiring the libraries to be specified using the
-short name, without any suffix appended to it. The `example' library in our
-case should be passed to the linker using -lexample, and not using -lexample_p.
-Based upon the shared, profile and debug variables, the makefile package will
-identify which are the libraries that exist on the system and it will come with
-the correct names when linking.
-
-The search order of libraries depending on what type of library is required is
-as follows. First of all an exact match is searched; if one is found it is
-returned. If either debug or profile are required, a library that matches at
-least one of these attributes is returned. For example if there is a
-profile+debug version of a library but only debug is required this library will
-match. If a static version is required but no static versions of the library
-exist, then no library is chosen; in this case the system simply prints out the
-name of the library, assuming a static library is somewhere else in the
-libraries search path of the linker.

+@node Memory Sanitisation, Library Types, Profile Information, Running Make
+@section Memory Sanitisation
+
+Production code must not use memory sanitization tools, but during development
+and debugging these can be extremely useful, so the Makefile Package provides
+an option to tell the compiler to generate output for address and leak
+sanitization using https://github.com/google/sanitizers/wiki/addresssanitizer
+
+Unfortunately, AddressSanitizer/LeakSanitizer is not particularly portable and
+is available on a limited selection of hardware and operating systems, so
+turning it on in GNUstep-make may not actually work on your system.  It is
+however very good with modern GCC or Clang on the most popular platforms.
+
+The following command illustrates how to tell the Makefile Package to pass
+the appropriate flags to the compiler so that sanitization is put into the
+binary and so that the preprocessor can be used to change code behaviour when
+it is built for sanitization (-fsanitize=address and -DGNUSTEP_WITH_ASAN=1).
+
+@smallexample
+make asan=yes
+@end smallexample
+
+You can get the same effect by setting an environment variable as follows:
+@smallexample
+export GNUSTEP_WITH_ASAN=1
+@end smallexample
+
+When you build libraries, frameworks, or bundles with sanitization turned on,
+you must also use ASAN to build any apps or tools which use them.  This
+is because the library/framework/bundle will have dependencies on the leak
+sanitization shared library, and those dependencies must be fulfilled when
+the app/tool is linked.
+
+The basic effect of sanitization is that, in the event of an address error
+(when the code attempts to access memory it shouldn't), the app/tool is
+immediately terminated with details of the problem printed to stderr, and
+in the event of memory leaks (detected at app/tool exit) a report of the
+locations of the leaks is printed to stderr.
+
+Beware that an app/tool built with ASAN maps a huge amount of virtual memory
+to help it detect memory violations in the code, and while this virtual memory
+usage does not require real memory, it does mean that processes monitoring the
+memory usage of your app/tool will give completely meaningless results.
+
+Beware also, that an app/tool built with ASAN does use considerably more real
+memory than normal, and its usage of memory continually grows, because it is
+keeping records of what the app/tool does with memory in order to be able to
+perform leak analysis and reporting when the app/tool finishes.
+If you have many apps/tools under test concurrently and for a long time, your
+system may run out of memory.

+1.1.2 Enabling Modern Objective-C Features
+---------------------
+
+GNUstep supports the legacy GCC runtime, and the modern libobjc2 runtime with
+Objective-C 2.0 Features such as ARC, Blocks (closures),  Synthesised property
+accessors, Efficient support for @synchronized() and more.
+
+   libobjc2 requires building with clang. If you've installed both clang and libobjc2
+you can configure GNUstep Make to use the newer runtime and features.
+Here is an example with the runtime version set to 2.2.
+(Set it to the last libobjc2 version to benefit from possible changes in Clang CodeGen).
+Please note that we explicitly enable some features such as objc-arc that might
+be infered from the runtime version.

-   of the form aaa-bbb-ccc where 'aaa' is the Objective-C runtime
-   library to use (examples are 'gnu' and 'apple'), 
-   'bbb' is the Foundation library to use (examples are 'gnu' for
-   gnustep-base, and 'apple' for Apple Cocoa FoundationKit),
-   and 'ccc' is the ApplicationKit to use (examples are 'gnu'
-   for gnustep-gui and 'apple' for Apple Cocoa AppKit).  Use this 
-   option if you want to force a different default library combo than 
-   the one that would be used by default.  For example, on Darwin GNUstep
-   will automatically use the Apple Objective-C frameworks by
-   default (library-combo=apple-apple-apple); if you are planning 
-   on installing and using gnustep-base on there, you would need 
-   to use --with-library-combo=gnu-gnu-gnu instead.  Please notice
-   that if --disable-flattened is used, gnustep-make can have fat
-   binaries that support multiple library combos.  In that case,
-   this flag will only configure the default one, but you can still
-   use other ones at run-time.
-   Please use 'ng-gnu-gnu' to build with 'next generation' cutting edge
