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.
