I think I'm getting close.  I found help in some shell examples in the
image converter, and copied the format.  I wrote "trim-header" to
accept a filename, and display to standard out. so:

(define-format html-with-header
  (:name "html with a extra header")
  (:must-recognize (lambda (x) (equal? (substring x 0 3) "Wik"))))

(converter html-with-header html
           (:shell "trim-header" from ">" to ))
;           (:shell "/home/temp3/trim-header" from ">" to ))

but when i do a "\include ./myfile" inside texmacs, i get "bad format
or data".  If i include a "normal" file, this dosn't happen, so the
auto-recoginiztion is working.

I set the first line of trim-header to display "i'm running" to
standard error, and tried running it, but the message never displays,
so i think "trim-header" is never running.  I tried turning security
off, and puting the bin in /usr/local, but no go.  I tried running it
at the bash command line, and it works fine, so it shouldn't be a
permission problem.  Any ideas what could be happening?
