Compiler Arguments and Switches

[MM]

Hello again :)

What does this mean ?
-inline
inline expand functions

I also saw the :
-release
compile release version, which means not generating code for contracts and
asserts

Now I get contracts. I though contracts were strange things that slow your
program down as they need to recheck every output. But it is only for testing
purposes, right?

I also don't really get the profiling part, but let me first read that a bit
more thoroughly :)
