piping message thru demime

I'm working on a macro to convert MIME messages not handled
correctly by slrn.

I'm using the perl script 'demime' if anyone knows it.  When I have
the macro working I'll post it so others can use, along with demime
installation instructions etc.

The macro below works:

define pipe_thru_demime ()
{
  pipe_article ("/usr/local/bin/demime - |
    /usr/local/share/vim/vim64/macros/less.sh '+set ft=mail' -");
}


but it just pipes the message to 'less' - what I want is to use
slrn's 'replace_article' function instead, but can't get that
working.

Below is my what I was thinking about doing, but keep getting
"S-Lang Error: Type Mismatch: Unable to typecast Integer_Type to
String_Type" error.

define demime ()
{
  replace_article (system (sprintf ("echo %s |
    /usr/local/bin/demime -", article_as_string ())));
}

Any ideas or pointers in the right direction?
