But who would want to start a _new_ emacs?

Here is a perl script that I use to ediff files in my (one-and-only
running) emacs:

---------------------------------------------------------------- edf.pl
#! /sw/local/bin/perl -w

sub filename2AbsFilename
{
    my $fn = shift(@_);

    if ( ! ($fn =~ '^/' ) )
    {
        return("$ENV{PWD}/$fn");
    }
    else
    {
        return($fn);
    }
}

$hostopt = "-h uhu";

if ( $#ARGV != 1 ) 
{
    print "$0: call ediff in emacs" , "\n";
    print "$0 --- usage: $0 file1 file2" , "\n";
    exit;
}

$file1 = shift;
$file2 = shift;

$file1 = filename2AbsFilename($file1);
$file2 = filename2AbsFilename($file2);

$COMMAND = "(raise-frame) (ediff-files \"$file1\" \"$file2\")";

system "gnudoit $hostopt \'$COMMAND\'";
----------------------------------------------------------------------

Maybe the hostname could be handeled in some more advanced way thatn
hard coding it in the script.
