# Check that our module compiles and can be "use"d.

# Check our module can be required. Very similar test to that above.

# There are a number of ways to generate the "ok" tests. These are:
# ok: first argument is true, second argument is name of test.
# is: first argument equals (eq) second argument, third argument is name of test.
# isnt: first argument does not equal (ne) the second, third is name of test
# like: first argument matches regexp in second, third is name of test
# unlike: first argument does not match regexp, third is name of test
# cmp_ok: compares first and third argument with comparison in second. Forth is test name.
