17.7.12 API Tests
-----------------

The 'testext' extension exercises parts of the extension API that are
not tested by the other samples.  The 'extension/testext.c' file
contains both the C code for the extension and 'awk' test code inside C
comments that run the tests.  The testing framework extracts the 'awk'
code and runs the tests.  See the source file for more information.
