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

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

DESCRIPTION
       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 "croak"s.

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