"""
This file is OBSCURE. Really. The purpose is to avoid copying and changing
-'test_c.py' from cffi/c/.
+'test_c.py' from cffi/c/ in the original CFFI repository:
+ https://bitbucket.org/cffi/cffi
+
+Adding a test here involves:
+1. add a test to cffi/c/test.py
+ - if you need a C function to call, add it into _cffi_backend.c
+ as a testfuncNN().
+2. have it pass when you run 'py.test test_c.py' in cffi
+3. check in and (if you can) push the changes
+4. copy test_c.py into _backend_test.py here, killing the few lines of header
+ - if you added a C function, it goes into _test_lib.c here
+ - if you could complete step 3, try running 'py.test test_file.py' here
+5. make the test pass in pypy ('py.test test_c.py')
