I have already modified a public domain copy of CTAGS ('C' Version)
and it is doing what I need (at least a first!) -- The function I am 
building
allow debug code to be installed in ranges of functions - of course with
all sorts of  "special inserts" at line numbers both absolute and relative.

It is intended to allow a full suite of debug code to be inserted in source
file without having to leave it there.  Since it will primarily key on 
computed
function boundaries, it should require only minor tweeking to insert its
code in later versions of the software (assuming maintence mode  or at
least semi-stable project).

Currently, for example I have inserted (successfully I might add) code
automatically in all functions in eval.c that prints the function name when
that function executes. A rather brute force feature, but it worked and
eval.c compiled and ruby ran without any hand tweaking at all.
 
Now this all theory -- God knows I could still find lot of aligators when
I drain this swamp. :-)

I will let you the result when I complete version 0.0.1...
