+===== Changing compilers =====
+The variables ''CC'' and ''CXX'' can be changed to modify the default C and C++ compilers respectively.
+So:
+<code>
+$ make CXX=clang++
+</code>
+will use clang++ as the C++ compiler for the build.
+===== Debug builds =====
+The C/C++ compilers are passed the ''C_COMPILER_OPTIONS'' environment variable. This is normally set to ''-O2'', but can be set to ''-g'' during the build process like this:
+<code>
+$ make C_COMPILER_FLAGS=-g
+</code>
+===== Standard test cases =====
+Standard test cases can be run using:
+<code>
+$ make runtest
+</code>
+For this to work properly, create test cases for your tool in the following way:
+   * All test cases and sample outputs are in the ''test/'' sub-directory.
+   * Test cases are run by changing to the ''test/'' sub-directory and running the script ''run.sh''. If this script doesn't exist, then nothing happens.
+Take a look at examples from existing ACT tools (e.g. ''[[https://github.com/asyncvlsi/actsim/tree/master/test|actsim]]'').
