Sys::Hostname - Try every conceivable way to get hostname

use Sys::Hostname;
my $host = hostname;

Attempts several methods of getting the system hostname and then caches the result. It tries the first available of the C library's gethostname(), `$Config{aphostname}`, uname(2), syscall(SYS_gethostname), `hostname`, `uname -n`, and the file /com/host. If all that fails it croaks.

All NULs, returns, and newlines are removed from the result.
