The canonical minimal test message in the C/Unix universe
or any of the minimal programs that emit this message.
Traditionally, the first program a C coder writes in a new
environment is one that just prints "hello, world" to standard
output (and indeed it is the first example program in K&R).
Environments that generate an unreasonably large executable
for this trivial test or which require a hairy
compiler-linker invocation to generate it are considered bad
(see X).
