Add --trace flag to mix compile

[Michał Muskała]

Hello everybody,

Today when something wired happens with compilation (like files recompiling when they shouldn't be), it's hard to even figure out what exactly is being compiled. I propose adding a --trace flag that would print a bit more information. At least it would be nice to get information about what files are being compiled, but it could also be interesting to see something more - for example why a file is being compiled making use of the compile-time dependancy information. This could greatly simplify debugging compilation issues.

Michał.

That always helps, so +1. The only question is if we should introduce a new flag or rather rely on MIX_DEBUG=1.

Some compilers display a little more when --verbose is used.
