+Other Useful Make Targets
+-------------------------
+
+Besides the default "all" and "test" targets, several other make
+targets are available which might prove useful for the casually
+adventurous Python builder.
+
+* profile-opt - This target works like the default "all" target, but
+  enables GCC profile generation. After compiling with
+  -fprofile-generate, it runs the test suite, then rebuilds with the
+  -fprofile-use flag. This extra step can boost performance of the
+  virtual machine by a modest (though worthwhile) amount. If this
+  works well for you, it is a worthwhile alternative to building the
+  "all" target.
+
+* coverage-report - This target rebuilds Python from scratch with the
+  relevant GCC coverage flags, executes the test suite, then generates
+  an HTML coverage report. This requires the lcov and genhtml
+  commands.
+
+* testall - Run the test suite twice, once with .pyc files, once
+  without.
