go weird, had to remove this. I should use trio soon for all the *printf()
stuff as this is too broken

better complains if there are missing input files for a test case
explaced exit-calls with returns instead

added lots of comments
added -s for short output and made it possible to run specific test cases
from the command line

dumps more information in case curl doesn't return success

since it has to survive http struct deletion

that it actually is our test server that runs

on paths

to return different sizes

"hang", it now results in an error instead
