I use this code with my plexus server (it does the work for me):

package inc;

sub init
    $main'ext{'hacked-html'} = 'text/hacked-html';
    $main'trans{'text/hacked-html'} = "text/html:inc'html";

sub html
    # this is a translation filter
    while (<STDIN>) {

sub inc
    local($_) = $_[0];
    return scalar(`$1`)                      if /^cmd="([^"]+)"/i;
    return "<pre>\n".scalar(`$1`)."</pre>\n" if /^precmd="([^"]+)"/i;
    return eval "$1"                         if /^perl="([^"]+)"/i;
    return scalar(`cat $1`)                  if /^file="([^"]+)"/i;
    return "<em>&lt;inc $1&gt; not understood</em>";
