Compiling tutorial examples

Hi,

I made a few Makefiles to make it easier to compile the tutorial 
examples ; the idea is that basically you enter a directory, type 
'make', run the tests, type 'make clean' then proceed to the next 
directory. They don't cover all directories (nor all examples), but they 
  still make things easier in quite a number of cases.

Would it be a welcome contribution to se?

PS: the archive is small (< 2k), but I'd rather not send it to the whole 
list ; tell me whom to send it if interested.
