	Ugh! I thought that the only reason people bothered with C++
was: new, del and iostreams.h!!!

	the current directory has to be in your path for this to work.
Since this is not a very good idea, you have to provide a path to the
executable. Typing ./a.out would run it.

	You know you can specify an output for your file, don't you? 
	g++ -o test test.cpp 
	produces an exec called test

	I thought that this was catered for automatically. Have a look
at <http://www.linuxdoc.org/HOWTO/Hardware-HOWTO-5.html>
