Hadrian questions

[Alp Mestanogullari]

Yes, this is on my TODO, along with a proper ./validate workflow (which 
combines binary distribution, installation and testing). I will do my 
best to provide a larger feature set in the upcoming weeks.

I twiddle something (say, the output file), and then I want to rerun the test. But now I have to go back out to the root of my tree to run the test, no? So: I think it would be very convenient to make a script we can all install (in our PATH) that will search for hadrian's build.sh and run it. Then, we can just say `build` (or whatever we name the script) anywhere in a tree. Of course, I could just do this locally, but I doubt I'm the only one who would enjoy it.
