First of all, because we won't be able to get LSB/FHS to update for us. It 
just won't happen. And even if we did get that, note that distributions are 
even more strict than LSB/FHS, since most of them don't use /opt either.

So this solution is better than updating because it's achievable. Possible is 
better than impossible.

Second, because updating LSB/FHS isn't enough either. The user still needs to 
find the Qt 5 qmake somewhere to get started. Updating the documentation to 
list the full path is worse than updating it to add a "-qt5" argument.

Managing a symlink in /usr/bin is not an acceptable solution because that 
requires administrator permissions and it breaks the ability to easily switch 
between Qt 4 and Qt 5.

I think we are keeping it simple. The current proposal is the simplest that 
still works.

If you can come up with something even simpler, I'll gladly accept it. The 
stuff you proposed before isn't acceptable because I shot holes through them.

Drop it.
