Contribution guide

The code is formatted using the K&R style of "indent".

indent -kr <files go here>

The C unit tests have also been indented in the same way, but manually adjsted such that the functions follow the normal libcheck layout.

START_TEST( ... ) {


}
END TEST

Indent tends to mangle the END_TEST macro, so that will need adjusting if indent is run over the test files again.
