I think I begin to understand. What you want has absolutely nothing
to do with .cf, I believe: If you say
\X'ps: file foo'
grops produces
BEGIN
<contents of foo>
END
However, you want to insert some stuff right after `BEGIN' and
directly before `END', right?
BEGIN
<hook before foo>
<contents of foo>
<hook after foo>
END
This could be implemented via \Y, using the yet-to-be-implemented
grops specials
ps: before-file
ps: after-file
