=head1 NAME
t/op/spawnw.t - Run OS commands and tell about the exit code
=head1 SYNOPSIS
% prove t/op/spawnw.t
=head1 DESCRIPTION
Tests spawning external commands.
spawnw does not capture STDOUT and STDERR from the spawned command.
So only the exit code can be tested.
The returned value is actually returned from the 'waitpid' system call.
In order to get the exit code from the spawned process, it needs to be right
shifted by 8 bit.
=head1 TODO
Test negative return codes.
=head1 SEE ALSO
The special variable $? in Perl 5.
