Okay, concrete examples then. I checked out your libc4 repository, and tried to build it. It doesn't even build, I get "error: conflicting types for 'c4suite_run'". (The code itself is a great mix of tabs and spaces with trailing whitespace for days, which to me is a red flag that it wasn't developed with attention to detail.)
The reason I was even trying to build the code is to get the output `./tests` produces, so I could rant about how difficult it would be for me to integrate this into e.g. Jenkins with decent feedback of which tests fail.
IMO, teamwork is essential, and I'd rather not work with somebody who is happy to put the burden on other developers just so he can save a bit of time by rolling his own. Thanks but no thanks.
