[m-dev.] A not-very-polite rant about "grades" and the build system.

Wow. I'm not on the Mercury team and I share your frustrations regarding
the build system (in fact, pretty much all of what you're saying is true),
but I gotta step in here... *this shit is not cool*.
I've been on the receiving end of some pretty pissed off entitled users in
my time, but I've never seen a rant like this about a free software
product. If you were a paying customer, you might rightly be upset, but
this would still be an inexcusable way to raise a complaint. As it is,
you're presumably just some dude on the Internet who downloaded some
software for free, got annoyed, and then swore your balls off at the
developers. That makes you an entitled jerk.
Here's a tip: when you're working with free software, the developers are
generally not obligated to do any work to either a) fix issues, or b) help
you with your problems. However, many open source projects will do (b), if
not (a), if you are polite about it. I understand the catharsis of writing
an angry rant when some software is behaving badly, but might I suggest
writing the rant, hovering over the "Send" button, considering the people
who might have to read said rant, and then deciding to rewrite it in a
polite and constructive manner?
You probably could have saved yourself some effort and made some friends if
you wrote a polite mail to this list in the first place, before you spent
two days trying to debug it yourself.
If they do fix this or update the documentation, I hope you will realise it
is *in spite of you* and not *because of you*.
PS. Your main complaint is answered in the second question in the official
