-for a description of the allowed make features and makefile guidelines.
+The build system uses [GNU autoconf][AUTOCONF] to create a simple POSIX makefile
+to build static and/or shared libraries.  To improve portability, makefiles
+*must not* make use of features unique to GNU make.  See the
+[Makefile Guidelines](#makefile-guidelines) section for a description of the
+allowed make features and makefile guidelines.

 An Xcode project is provided for macOS/iOS developers, and a Visual Studio
 solution and projects for Windows developers.

 The following standard targets are defined in the makefile:

 - `all`; creates the static library and unit test program.
- `all-shared`; creates a shared library appropriate for the local system.
 - `clean`; removes all target programs libraries, documentation files, and
  object files,
- `debug`: creates a clean build of the static library and unit test program
-  with debug printfs and the clang address sanitizer enabled.
 - `install`; installs all distribution files in their corresponding locations.
- `install-shared`; same as `install` but also installs the shared library.
- `macos`; same as `all` but creates a Universal Binary (X64 + ARM64).
 - `test`; runs the unit test program, building it as needed.
